Question

When the function below is graphed, how many x-intercepts does it have?y = 4x2 - 12x + 9?

Answer 1

It is 1 if using apex

Answer 2

Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0)
then 0 =4x^2 -12x + 9
0=(2x-3)(2x-3)
0=2x-3
so x=3/2 that is x-intercept
