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

ANSWER

EXPLANATION

The graph of the function that will have a maximum and a y-intercept of 4 is

To check for the y-intercept, we put x=0 into the function.

This implies that,

We can see that the coefficient of the quadratic term is -1.

Since the coefficient of the quadratic term is less than zero, the graph will have a maximum point.
