Question

Solve for f(-2)
f(x) = -3x + 3
f(-2) = -3(-2) + 3
f(-2) = ?​

Answer 1

Functions =

in the next step, we can do that :

f(-2) = -3(-2) + 3

f(-2) = 6 + 3

f(-2) = 9

answer f(-2) = 9

note :

if the number is negative, multiply by a negative number as well, then the result is a positive number.
