Question

Y = x2 + 4x – 117 i need to know the roots and vertex

Answer 1

Answer:

Vertex : (-2,-121)

Roots : x=9,-13

Step-by-step explanation: Rewrite the vertex form and use this form to fine the vertex (h,k).

The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with zero and solve for x.

I hope this helps you out.
