Question

Find the vertex, the equation of the axis of symmetry, and the y-intercept of the graph of each function.

y=x^2-9

Answer 1

idk

Explanation:

Answer 2

Explanation:

y=(x-a)^2+b

axis of symmetry is x-a=0 or x=a

vertex is (a,b)

y-intercept is y=b

Here eq. of axis of symmetry is x=0 or y-axis.

y -intercept is -9
