Answer 1

Generate a table:
\[-5 \le x \le 5\]\[f(x) = -(x)^{2}-2\]

Answer 2

x=1--->f(1)=-1-2=-3
x=2--->f(2)=-4-2=-6
and so on...

Answer 3

I'm just asking for a rerfresher, but wouldn't \[-5\le x \] be \[x \ge -5\]

Answer 7

So my input will be anything between -5 and 5?

Answer 8

Answer 9

itis vry simple, ince your funion is a parabola, so it is symmetric with respect to the y-axis, namely:
