Determine the vertex. Plot the vertex and several points. Draw the parabola as an upward facing curve.

Explanation:

y=(x-3)^2+5 is in the vertex form of a parabola, y=(x-h)^2+k, where h=3 and k=5. The vertex of this parabola is (h,k)=(3,5).

Find some points by substituting values for x, making sure to include both positive and negative values.

x=-2, y=30
x=-1, y=21
x=0, y=14
x=1, y=9
x=2, y=6

Plot the vertex, and then some points. Draw a graph as a curve where the curve turns at the vertex (3,5).
