This worksheet is about the shapes of quadratic graphs.

All are parabolic but their equations can be used to identify their shapes quickly and easily.

We start with the basic function f(x) = x², or the graph of the *parabola ***y = x².**

**Vertical shifts**

We get equations of the form y = x² ± k

**Horizontal shifts**

We get equations of the form y = (x ± k)²

**Stretching**

We get equations of the form y = kx²
