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
