Question

given the function f(x) = -2x - 8, find the following values
a. f(0)
b. f(x)
c. f(-x)
a. f(0) = \square (simplify your answer.)

Explanation:

Step1: Substitute $x=0$ into $f(x)$

$f(0) = -2(0) - 8$

Step2: Simplify the expression

$f(0) = 0 - 8 = -8$

Step3: Substitute $x=s$ into $f(x)$

$f(s) = -2(s) - 8$

Step4: Simplify the expression

$f(s) = -2s - 8$

Step5: Substitute $x=-x$ into $f(x)$

$f(-x) = -2(-x) - 8$

Step6: Simplify the expression

$f(-x) = 2x - 8$

Answer:

a. $-8$
b. $-2s - 8$
c. $2x - 8$
