Question

Find the x-intercepts of the parabola with

vertex (-1,-16) and y-intercept (0, -15).
Write your answer in this form: (X1 Y1), (X2 Y2).
If necessary, round to the nearest hundredth.

Answer 1

Standard Form: y = − x 2 − 15

Vertex Form: y = − 1 x 2 −15

Explanation:

Find the parabola through ( − 1 , − 16 ) with vertex ( 0 , − 15 ) using the vertex form

y = ( x − h ) 2 + k

Getting you

SF: y = − x 2 − 15

VF: y = − 1 x 2 − 15

Hope this helps
