Answer:
The function is equal to 
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to

where
a is a coefficient
(h,k) is the vertex
In this problem we have
(h,k)=(8,-1)
substitute

<u><em>Find the value of a</em></u>
Remember that we have the y-intercept
The y-intercept is the point (0,-17)
substitute
x=0,y=-17






therefore
The function is equal to
