we use for evaluating at x = 3?

Fill in the blank:  f(3) = [___] + 4
Choose the correct value:  f(3) = ___

Which half of the formula for f(x) do
we use for evaluating at x = –1?
Fill in the blank:  f(–1) = 2[___] 2 – 1
Choose the correct value:  f(–1) = ___
Then f(3) – f(–1) = [___]

Your score is:
