Answer: y=-2(x+3)^2-2

Explanation:

A general form of a parabola is as follows:

y=a(x-x_0)^2+y_0

where the point (x_0,y_0) is the vertex. We know that is (-3,-2), so:

y=a(x+3)^2-2

The remaining unknown is the coefficient "a" and we determine it using the extra point given at (-5,-10). The parabola equation must satisfy this point otherwise the point cannot lie on the parabola:

-10=a(-5+3)^2-2\\-10=4a-2\\\rightarrow a=-2

And so we obtain the equation of the parabola:

y=-2(x+3)^2-2

No, since it a repeating(terminating) decimal, so it is not a rational number.
