We know that the graph goes in units of 1.
We know that the roots are -1 and 4. (Just assume it's accurate and not off by 0.0000000001.)
We can set it up as an equation: -1(x+1)(x-4) = y (I added -1 because there are two parabolas that go through those points on the x-axis, and since this parabola is facing down, I must add a negative a value.
Then multiply (F.O.I.L. - First, Outer, Inner, Last)
x^2 -4x + x - 4 = -(x^2 - 3x - 4) = -x^2 + 3x + 4
Then using -(b/2a) solve for vertex: -(3/-2) = 3/2
Plug 3/2 back into the equation.
-(3/2)^2 + 3(3/2) + 4 = -9/4 + (9/2) + 4 = 25/4
The vertex would be: (3/2, 25/4)
Axis of symmetry would be: x = 3/2

Answer:
169
Step-by-step explanation:
Add: 9 + 4 = 13
Exponentiation: the result of step No. 1 ^ 2 = 13 ^ 2 = 169
Divide: 15 / 3 = 5
Subtract: 5 - the result of step No. 3 = 5 - 5 = 0
Add: the result of step No. 2 + the result of step No. 4 = 169 + 0 = 169
