11-74.

Change each equation to graphing form. Sketch the graph and label each vertex and axis of symmetry. Homework Help ✎

*y*= 2*x*^{2}+ 7*x*– 7*y*= 3*x*^{2}–*x*– 8

Add 7 to both sides to isolate the *x*-terms.

Factor out a 2 from the *x*-terms.

Complete the square. Remember to add to both sides.

Simplify.

Where is the vertex? Axis of symmetry?
