Question

a function is shown.
$f(x) = 7 - 4x$
what is the value of $f(-5)$?
a 27
b -13
c -15
d 140
12.

Explanation:

Step1: Substitute \( x = -5 \) into \( f(x) \)

Given \( f(x) = 7 - 4x \), replace \( x \) with \( -5 \):
\( f(-5) = 7 - 4(-5) \)

Step2: Simplify the expression

Calculate \( -4(-5) = 20 \), then add to 7:
\( f(-5) = 7 + 20 = 27 \)

Answer:

A. 27
