Question

Given the function f(x)=4x−8 what is the value for f(2)? Enter ONLY the final number.

Answer 1

if I’m not wrong it should be

f(2) = 8 - 8 = 0.

Answer 2

Answer: f(2) = 0

Explanation:

We're asked to evaluate the following function for f(2) :

⇒ f(x) = 4x - 8

Substitute 2 into the function :

⇒ f(2) = 4(2) - 8

Evaluate :

⇒ f(2) = 8 - 8

Subtract :

⇒ f(2) = 0

Therefore f(2) = 0
