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

see the attached figure to better understand the problem
Answer:
Step-by-step explanation:
12) x is greater than -15
14/15) you would add four to both sides
16) Closed dot on 7 and everything less than that is X
10) A
The answer is 5 hope it helps
The function is not linear because the slope is not constant. I am pretty sure that it is an exponential function, since the line approaches 0 but never touches it, and it grows exponentially. The exponential parent function is f(x)=b^x.
Hope this helped.
