Question

If f(-2)=-4, then the point ________ is on the graph of f.

Answer 1

Answer:   (-2, -4)

Explanation:

We have y = f(x) where x is the input and y is the output.

Any point is of the form (x,y)

Writing f(-2) means x = -2 is plugged into f(x), which results in an output of -4 because f(-2) = -4.

So we have (x,y) turn into (-2, -4)
