Find the requested function value.

Find (f ∘ g)(-9) when f(x) = 9x + 5 and g(x) = -4x2 - 6x + 3.

A.-2398

B.-22,645

C.763

D.842

Given:

Given that the functions and

We need to determine the value of the function

First, we shall determine the value of the function

The value of the function :

Let us determine the value of the function

Thus, we have;

Thus, the value of the function is

The value of the function :

The value of the function can be determined by substituting x = -9 in the function

Thus, we have;

Thus, the value of the function is -2398

Hence, Option A is the correct answer.

answer: it is 1: 47 pm

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
