Question

State the following key features of these quadratic functions Please Thank you so much!!!

Answer 1

1) vertex=(4,-1), domain=
`(-\infty,\infty)`, range=
`[-1,\infty)`, x-intercepts: x=3,5,

y-intercept: y=15, axis of symmetry: x=4

congruent equation:
`y=x^(2)-8x+15`

2) vertex=(-1,12), domain=
`(-\infty,\infty)`, range=
`(-\infty,12]`, x-intercepts: x=-3,1,

y-intercept: y=9, axis of symmetry: x= -1

congruent equation:
`y=-3(x-(-1))^(2)+12`

Explanation:

The explanation is attached below.
