Answer:
f(x) = -2x² + 2
Step-by-step explanation:
If you remember the y = x² parent graph, you will be able to derive your equation from visualization.
The vertex of this graph would be at (0, 2), so your degree coefficient would be negative. Your y-intercept would also be at (0, 2). Since both 1 and -1 are included, you can tell it is a parabola, and hence the 3rd option is your answer.
If its to number 9, it's ∈35.48
Wouldnt it be:
9 9
--- = -------- = 9
3-2 1
Sorry I don’t now the answer to this problem
