If <u>quadratic function </u>y=ax^2+bx+c has <u>vertex </u>that is the same as its <u>y-intercept</u>, then

x_v=-\dfrac{b}{2a}=0,\\ \\b=0

and its equation is y=ax^2+c.

The graph of this quadratic function is translated graph of the function y=ax^2 up or down (depends on c).

This means  that there could be

  • two x-intercepts;
  • one x-intercept;
  • no x-intercepts.

The axis of symmetry of the graph of the function y=ax^2 is x=0 (y-axis).

Answer: correct choice is A
