Answer:
f(x) = 2x² + 4x - 16
= 2(x² + 2x) - 16
= 2(x² + 2(x)(1) + 1² - 1²) - 16
= 2(x + 1)² - 2 - 16
= 2(x + 1)² - 18
Vertex: (-1, -18) minimum
Second point can be the y-intercept:
(0, -16)
It should be a concave up
48=16-0.5x
add 0.5 both sides
0.5x+48=16
mnus 48 boh sides
0.5x=-32
times 2 both sides
x=-64
