Find the requested function value.

liq [111]

Given:

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 $(f \circ g)(x)$

The value of the function $(f \circ g)(x)$ :

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

The value of the function $(f \circ g)(-9)$ :

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.

Which of the following functions is not a linear

kicyunya [14]

By looking at the degree of the polynomials, we conclude that the option that is not linear is option C.

<h3>Which of the following functions is not a linear function?</h3>

A polynomial is an expression of the form:

$p(x) = a_n*x^n + a_{n-1}*x^{n-1} + ... + a_0$

Where all the exponents are natural numbers.

We define the degree of a polynomial as the largest exponent, and we define a linear function as a polynomial of degree 1.

So a linear function is of the form:

$f(x) = a_1*x + a_0$

Now, if you look at option C, you can see that the degree of that polynomial is 2. So that is not a linear function.

Then the correct option is C.
