Front

If f(x) = x², what is g(x) if it is transformed to g(x) = (x - 3)²?

Back

g(x) = (x - 3)² represents a shift left 3.

Front

Front

What does it mean for a function to be 'narrower' than another?

Back

A function is narrower if it has a larger coefficient in front of x².

Front

What is the vertex form of a quadratic function?

Back

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