Question

At how many points does the graph of the function below intersect the x-axis? Y=3x2-8x+8

Answer 1

It does not intersect x-axis.

Explanation:

It would intersect x-axis when y=0.

Let's try to find it determinant
`D=b^(2) -4ac=8^2-4*3*8=64-12*8=-32` It is bellow zero, so there is no solution.
