Q:
# The graph of which function will have a maximum and a y-intercept of 4? f(x) = 4x2 + 6x – 1 f(x) = –4x2 + 8x + 5 f(x) = –x2 + 2x + 4 f(x) = x2 + 4x – 4

Accepted Solution

A:

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 + 4The y-intercept occurs when x = 0 soy-intercept = 0 + 0 + 4 = 4.-
