Topic:
Symmetry
Axis of symmetry and coefficients of a quadratic Adjust the coefficients of the quadratic.

"a"

What are the effects of "a" in the graph of the quadratic?

"c"

What are the effects of "c" in the graph of the quadratic?

"b"

What are the effects of b on the graph of the quadratic?

Axis of symmetry

When a1, how do a and b effect the axis of symmetry?
