Question

Given f(x) = 3x - 1, find f(2).

Answer 1

so when finding f of x you would want to replace 2 for all the Xs bc that’s what you’re trying to find basically so you would do
f(2)=3(2)-1
which equals 5

Answer 2

5

Explanation:

by plugging on the number 2 to the equation, solve 3×2=6 and then subtract 1=5
