PLEASE HELP

Find the x-intercepts of the parabola with vertex (-4,2) and y-intercept (0,-30).
Write your answer in this form: (x1,y1),(x2,y2).
If necessary, round to the nearest hundredth.

Use the method of completing the square to write the equation of the given parabola in this form:

(y – k) = a(x – h)2

where a ≠ 0, (h,k) is the vertex, and x = h is the axis of symmetry.

mathmale · Answer

Vertex:  What are the values of the parameters h and k?

Point on the graph:  the y-intercept:  What are the coordinates of this point?

Insert all of the given info; this will enable you to calculate the coefficient, "a."
