Which of the following is the function F(x) if F^-1(x) = x+4/11?

Marianna [84]

Answer:

B. F(x) =X-4/11

Step-by-step explanation:

We are given the inverse function;

f^(-1)(x) = x + 4/11

Thus means, x was replaced with y and vise versa. Thus;

x = y + 4/11

Lets make y the subject;

y = x - 4/11

Thus,in inverse of a function we replace y with f(x) for the original function or f^(1)(x) for the inverse.

Thus, putting f(x) for y gives;

f(x) = x - 4/11

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv

SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

$y=-x^2+64x-292$

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

$y = ax^2 + bx + c$

and its maximum is:

$Max = \frac{-b}{2a}$

So: $y=-x^2+64x-292$

We have that

$a = -1$

$b = 64$

$c = -292$

$Max = \frac{-b}{2a}$

$Max = \frac{-64}{2 * -1}$

$Max = \frac{-64}{-2}$

$Max = 32$

<em>Hence, the maximum amount of profit is 32</em>
