Answer:

f(2) = -4

Step-by-step explanation:

Plug in 2 for x:

f(x) = 4x - 12

f(2) = 4(2) - 12

Remember to follow PEMDAS. (PEMDAS = Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction) PEMDAS is what you follow to solve these questions.

First, Multiply:

f(2) = 4(2) - 12

f(2) = (4 * 2) - 12

f(2) = 8 - 12

Next, subtract:

f(2) = 8 - 12

f(2) = -4

f(2) = -4 is your answer.
