All parabolas are symmetric with respect to a line called the axis of symmetry. a parabola intersects its axis of symmetry at what point?
a. vertex
c. translation
b. function
d. y-intercept

a. vertex

Step-by-step explanation:

The vertex of the parabola is the point where the two arms of the parabola grow, and it is where the parabola originates and it also creates the axis of symmetry, in depending on if the parabola is on growing on the x or the y axis, the X or Y from the vertex will be the axis of simmetry.
