Question

Given f(x) = 2x - 1, find the value of f(2).

Answer 1

how to do

Answer 2

f(x) = 2x - 1 and you are trying to find f(2)
So, I believe you would plug in 2 into the x values.

Answer 3

is asking you if you put a 2 for every x what do you get?

Answer 4

So, 2(2) -1 = f(2)

Answer 5

2 times 2 is 4 minus 1 is 3

Answer 6

than 3 times 2?

Answer 7

So f(2) = 3. You're right! Good job!
