Therefore , the solution to the given problem of function comes out to be ss a result, Rolle's Theorem remains true.

Mathematics deals with numbers and their variants, formulae and associated structures, geometries and their areas, and locations where they might be found. The term "function" describes the connection between a group of input, of which each has a corresponding output. A function is an association among inputs and outputs where each input results in a single, unique output. A realm as well as a codomain, or scope, are assigned to each function. Functions are typically denoted by the letter f. (x). The input is an x. On activities, one-to-one activities, many-to-one functions, within operations, and on functions are the four main categories of functions that are available.

Here,

Consider

f(-1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0

and f(1)=1-[tex](-1 )^{\frac {2}{3}}[/tex]=0

So, f(-1)= f(1) (1)

As a result of differentiating f(x) with regard to x, we now have

f'(x)= -2 / 3

Consequently, f'(0) is false.

So, at 0inleft (-1,1 ), f cannot be deduced.

Therefore, the given function in the range (-1,1) does not satisfy Rolle's theorem.

As a result, no c exists in (-1,1) for which f'(c )=0 even though f(-1)=f(1 ).

As a result, Rolle's Theorem remains true.

Answer:

We can start solving the problem by using a system of equations. Let x be the number of pieces of fruit on a small tray, and y be the number of pieces of fruit on a large tray.

From the information given, we know that:

Yesterday: x + 4y = 166 (1)

Today: 4x + 4y = 232 (2)

We have two equations and two unknowns, so we can use substitution to solve for one variable in terms of the other, and then substitute that back into the other equation.

From equation (1) we can solve for x:

x = 166 - 4y

Now we can substitute this into equation (2)

4(166 - 4y) + 4y = 232

Simplifying and solving for y:

-672 + 16y = 232

16y = 904

y = 56.5

This means that each large tray has 56.5 pieces of fruit.

Now we can substitute this value back into the first equation:

x + 4(56.5) = 166

x = 166 - 226

x = -60

This solution doesn't make sense, because the number of pieces of fruit can't be negative. This means that there is no solution to the system of equations, and it is impossible to determine the number of pieces of fruit on each size tray based on the information given.

Step-by-step explanation:

The probability that the hospital has 7 fatalities this week is approximately 0.0199

The probability that the hospital has 7 fatalities in a week, given an average of 7 fatalities per week, can be calculated using the Poisson distribution. The Poisson distribution is a discrete probability distribution that models the number of events (in this case, fatalities) that occur in a fixed interval of time (in this case, a week) with a certain average rate (in this case, 7 fatalities per week). The probability of k events happening in a given interval of time is given by the following formula:

P(k;λ) = (e^(-λ))*(λ^k)/k!

Where λ is the average number of events per interval of time and k is the number of events we are interested in.

In this case, we are looking for the probability that there are 7 fatalities this week, given that the average number of fatalities per week is 7. So we can plug in the values into the equation:

P(7;7) = (e^(-7))(7^7)/7! =0.149

c) The x-intercepts are; √2 - 3, and -√2 + 3

d) y-intercept is (0, -14)

e) The domain is the set of all real numbers

The range is (-∞, 4]

A function is a rule that maps an input value unto an output, such that each input has exactly one output.

A quadratic function is a function of the form; y = a·x² + b·x + c

a) The function [tex]y = \dfrac{1}{x^2+5} -3[/tex], when simplified, we get;

[tex]y = \dfrac{1 - 3\cdot x^2 - 15}{x^2+5}[/tex], which is a rational polynomial.

Therefore, the function is not a quadratic function.

b) x² = y - 1

y = x² + 1

The above function is in the form; y = a·x² + b·x + c, where;

a = 1, b = 0, c = 1

c) y = 3·x - 7 + 4·x²

The above function is in the form y = a·x² + b·x + c, where;

a = 4, b = 3, and c = -7

d) The function y = 6·x - 3·√x can be expressed as; √x = z

Therefore; z² = x

Therefore; y = 6·x - 3·√x = 6·z² - 3·z

y = 6·z² - 3·z

The above function is a quadratic function, therefore, the function;

y = 6·x - 3·√3 is a quadratic function

2. The function y = -2·(x + 3)² + 4 is in the vertex form of the equation of a quadratic equation; y = a·(x - h)² + k

Where;

a = The leading coefficient

(h, k) = The coordinates of the vertex

Comparing the values, we get;

The vertex, (h, k) = (-3, 4)

a = -2

When x = 0, we get; y = -2·(0 + 3)² + 4 = -2 × 9 + 4 = -14

With a vertex of (-3, 4), we get;

When x = -6, y = -14

The graph can be obtained by drawing a parabola with vertex at (-3, 4), and passing through the points (0, -14), and (-6, -14)

Please find attached the graph of the function y = -2·(x + 3)² + 4, created with the points (0, -14), (-6, -14), and vertex point (-3, 4), created with MS Excel

a) The axis of symmetry is the line about which the graph is symmetrical

The axis of symmetry is the line x = -3

b) The maximum value is the vertex of the graph, which is the point (-3, 4)

c) The x-intercept are the point the graph intersects the x-axis, which are obtained by plugging in y = 0, as follows;

y = 0 = -2·(x + 3)² + 4

(x + 3)² = -4/(-2) = 2

x + 3 = ±√(2)

x = ±√(2) - 3

The x-intercepts are; x = √2 - 3, and -√2 - 3

d) The y-intercepts are the point the graph intersects the y-axis, which is the point where x = 0

Therefore, the y-intercept is the point (0, -14)

e) The domain is the set of possible input values or x-values

The domain of the function, as presented in the graph is the set of all real numbers

The domain is; (-∞, ∞)

The range is the set of the possible y-values
