Question

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

Answer 1

vertex form for equation of a parabola
f(x) = a(x-h)^2 + k vertex (h, k)

Answer 2

x-intercept when f(x) = 0
y-intercept when x = 0
given y-intercept (0, -30)
