Answer:
6
Step-by-step explanation:
f(x) reads "the function at the value of x". If we are looking at f(2) we are looking at "the function at the x-value of 2". Therefore, f(2) is
f(2) = 3(2) - 1
f(2) = 6 - 1
f(2) = 5
Likewise,
f(0) = 3(0) - 1
f(0) = 0 - 1
f(0) = -1
So f(2) - f(0) is
5 - (-1) which comes out to 6
