Answer:
The vertex is (-4,-18)
Step-by-step explanation: Given in ax² + bx + c form
To get the x value, use the formula [tex]x=\frac{-b}{2a}[/tex]
a is 1 (implied) b is 8 x= -8/2 so x is -4
Plug in to the equation ans solve for y. "f(x)" means"y output"
y = (-4)² + 8(-4) - 2
y = 16 -16 -2
y = -18
so the coordinates of the vertex: (-4, -18)
