Question

At how many points does the graph of the function below intersect the x-axis?

Answer 1

Answer:

A.0

Step-by-step explanation:

y=4x²- 9x + 9

The function will intersect the x-axis when  y = 0.

4x² - 9x + 9 = 0

a=4, b= -9, c=9

D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63

D= -63, D<0, so the equation

4x² - 9x + 9 = 0 does not have real roots. That means that function    y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.
