Question

josue is practicing evaluating functions. he is using the following functions.
$f(x) = -6 + 14x$
$g(x) = (2x + 9)^2$
he evaluates the functions for $f(7)$ and $g(-3)$. what values will he calculate? select two correct answers.
a. 9
b. 225
c. $-28$
d. 104
e. 92

Explanation:

Step1: Substitute $x=7$ into $f(x)$

$f(7) = -6 + 14(7)$

Step2: Calculate $f(7)$

$f(7) = -6 + 98 = 92$

Step3: Substitute $x=-3$ into $g(x)$

$g(-3) = (2(-3) + 9)^2$

Step4: Simplify inside the parentheses

$g(-3) = (-6 + 9)^2 = (3)^2$

Step5: Calculate $g(-3)$

$g(-3) = 9$

Answer:

A. 9
E. 92
