Question

which must be true of a quadratic function whose vertex is the same as the y-intercept ?
The axis of symmetry for the function is x=o
The axis of symmetry for the function is y=0
The function has no x-intercepts
The function has 1x-intercept

Answer 1

A quadratic function whose vertex is the same as the y-intercept has the equation
y=x^2+k   (where k is the y-intercept, with vertex (0,k))

Since the vertex coincides with the y-intercept, the axis of symmetry is x=0.

Answer 2

Answer:

A. The axis of symmetry for the function is x = 0.
