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.
