Question

Please help I am terrible at algebra

Answer 1

Equation of parabola is $y=(x+10)^{2}$.

Step-by-step explanation:

The vertex form of the parabola is given as, $y=a(x-h)^{2}+k$

where (h,k) is the vertex of the parabola.

If the parabola must be symmetric about x = -10 then the axis of symmetry must be x = -10.

To execute this, h should be -10, and it was plugged in the vertex form of the parabola, a and k may be any real number.

So the equation can be written as,  $y=(x+10)^{2}$
