Rita graphed the step function below. which values on the graph are equivalent? f(–1) and f(–2) f(1) and f(0) f(–3) and f(–2.1) f(2) and f(1.9)

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
