In a quadratic function you square x so I'd assume that's what they want.
That means the values of f(x) would be:
9
1
1
9
25
Hi there! The answer is A.

In the graph we can see is a parabola (so B. cannot be the answer) with a vertex at the point (0, 0), which means the parabola is not translated upwards or downwards. Therefore, only A. can be correct, since all the other formulas include a translation downwards (which can be deduced from the -2 in the formula).
Answer:
i don't know I'm realy sorry but u will get eventually
