Front

What does it mean to find f(2)?

Back

Let x = 2

Front

If f(x) = 2x + 1, what would be your first step to find f(1)?

Back

Plug a 1 in for all the x's

Front

If f(x) = 2x+1, what would the function look like once you substitute in a 1 to find f(1)?

Back

f(1) = 2 (1) + 1

Front

If f(x) = 2x + 1, find f(1).

Back

f(1) = 3
