Factored form {y=a(x+r)(x-b)}
To find the A.O.S you add the two x-intercepts and divide them by two.
AXIS OF SYMMETRY
This is the vertical line that spilts the parabola down the middle
Vertex form {y=a(x-h)²+k}
The A.O.S. is the h value in the expression y=a(x-h)²+k
Standard Form {y= ax² + bx +c}
To find the A.O.S you average out the x intercepts by substracting them
