4x - 8y = 8
8y = 4x - 8
y = 1/2 x - 1
slope: 1/2
y-intercept:(0, -1)
Line perpendicular- negative reciprocal slope
y-(-1) = -2 (x-0) Hahaha I don't know what is the point slope form though hahaha not sure with this.

Answer:
It is f(x) = -x^2 + 2x + 4.
Step-by-step explanation:
As it has a maximum the coefficents of x^2 will be negative.
f(x) = -x^2 + 2x + 4
The y-intercept occurs when x = 0 so
y-intercept = 0 + 0 + 4 = 4.
