Answer:
It is hard to understand the question but the way its typed but I tried my best.
h(x) = -x²+2x
axis of symmetry: x=1
y-intercept: (0,0)
x-intercept: (0, 0) and (2, 0)
maximum: (1, 1)
g(x) = x²+6x+8
axis of symmetry: x=-3
y-intercept: (0, 8)
x-intercept: (-4, 0) and (-2, 0)
minimum: (-3, -1)
Cant tell what f(x) is but graphing it on demos helps.
