Vertex form for a parabola with vertex (p,q) is

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>



Putting it together,
Answer: 
We could multiply that out if we like but I won't bother.
Remember to follow PEMDAS, and left -> right rule.
First, solve the Parenthesis:
(4 + 2^3)
Solve the exponent.
2^3 = 2 x 2 x 2 = 4 x 2 = 8
4 + 8 = 12
_______________________________________________________________
(5^2) x (12)
5^2 = 5 x 5 = 25
25 x 12
_______________________________________________________________
Multiply
25 x 12 = 300
________________________________________________________________
300 is your answer
