Front

What is the vertex form of a quadratic function?

Back

y = a(x - h)² + k, where (h, k) is the vertex.

Front

What does it mean for a function to be increasing?

Back

A function is increasing on an interval if, for any two points in that interval, the function value at the second point is greater than at the first.

Front

What is the difference between even and odd functions?

Back

Even functions are symmetric about the y-axis; odd functions are symmetric about the origin.
