Answer:
y=-(x+11)(x-23)
Step-by-step explanation:
y=-(x+11)(x-23)
use the x intercepts they give you, and make it the opposite i.e. if it positive, then make it negative if it is negative make it positive
i.e. -11 equals 11
thus (x+11)
then, the graph is concave down, so it is negative at the front
