Find the requested function value.

liq [111]

<u>Given</u>:

Given that the functions $f(x)=9 x+5$ and $g(x)=-4x^2-6x+3$

We need to determine the value of the function $(f \circ g)(-9)$

First, we shall determine the value of the function $(f \circ g)(x)$

<u>The value of the function </u> $(f \circ g)(x)$ <u>:</u>

Let us determine the value of the function $(f \circ g)(x)$

Thus, we have;

$(f \circ g)(x)=f[g(x)]$

$=f(-4x^2-6x+3)$

$=9(-4x^2-6x+3)+5$

$=-36x^2-54x+27+5$

$(f \circ g)(x)=-36x^2-54x+32$

Thus, the value of the function is $(f \circ g)(x)=-36x^2-54x+32$

<u>The value of the function </u> $(f \circ g)(-9)$ <u>:</u>

The value of the function $(f \circ g)(-9)$ can be determined by substituting x = -9 in the function $(f \circ g)(x)=-36x^2-54x+32$

Thus, we have;

$(f \circ g)(-9)=-36(-9)^2-54(-9)+32$

$=-36(81)-54(-9)+32$

$=-2916+486+32$

$(f \circ g)(-9)=-2398$

Thus, the value of the function $(f \circ g)(-9)$ is -2398

Hence, Option A is the correct answer.

The area is (2x + 15) square centimeters.

emmainna [20.7K]

Answer:

$Area\:shaded=\frac{3}{5} (2x+15)$

Step-by-step explanation:

Let $s$ be the shaded area and $u$ be the unshaded area, then we know that

(1). $\frac{s}{u}=\frac{3}{2}$

and

(2). $s+u=(2x+15)$

We solve for $u$ in the first equation and get:

$u=\frac{2}{3}s$

and put this into the second equation and get:

$s+\frac{2}{3}s=(2x+15)$

$s(1+\frac{2}{3} )=(2x+15)$

$s(\frac{5}{3} )=(2x+15)$

$\boxed{s=\frac{3}{5} (2x+15)}$
