2-65.

Calculate f (−3) for each function below. Homework Help ✎

1. f(x) = −2x + 3

Substitute −3 for x and then simplify.

2. f(x) = 4x

Substitute −3 for x and then simplify.

$f(-3)=4^{-3}$

$f(-3)=\frac{1}{4^{3}}$

3. f(x) = x−2 + 1

See Hint for part (a).

4. f(x) = x + 2

See Hint for part (a).

$\frac{1}{2}$
