Question

Describe how the graph of y=-x^2 1 differs from y=-x^2. The find the axis of symmetry and the vertex.

Answer 1

I have attached the graphs
Equation one axis of symmetry is y=0 and vertex is (0,1)
Equation two axis of symmetry is y=0 and vertex is (0,0)

The +1 in the first equation shifted the graph up one point.

Hope that helps
