Question

Explain the effect that "a" has on the function f(x) = a(x − h)2 + k.Answer

The "a" compresses (a < 0) or stretches (a > 0) a quadratic function.

The "a" moves the function left (a < 0) or right (a > 0).

The "a" moves the function up (a > 0) or down (a < 0).

The "a" reflects the graph across the y-axis.
