Function Test Review Alg 1

Front

Find f(-1) for the function f(x) = 2x + 1.

Back

f(-1) = 2(-1) + 1 = -2 + 1 = -1.

Front

Find f(-3) for the function f(x) = 5x + 2.

Back

f(-3) = 5(-3) + 2 = -15 + 2 = -13.

Back

It means that at least one input is associated with more than one output.

Front

Find f(2) for the function f(x) = x^2 - 4.

Back

f(2) = 2^2 - 4 = 4 - 4 = 0.
