Which of the following best describe the graph of a quadratic equation with one real root?

A: It has 2 x-intercepts
B: It does not cross the x-axis
C: Its vertex lies on the x-axis
D: Its vertex lies on the y-axis

It could be either C or D.

x = ay^2 has a vertex on the y axis.

y = bx^2 has a vertex on the x axis.

a and b are constants
