Looking at the graph

Part a

This is a vertical parabola that opens Upward

Part b

The equation of the axis of symmetry is equal to the x-axis of the vertex (in a vertical parabola)

The vertex is the point (-3,3)

so

the equation of the axis of symmetry is x=-3

Part c

The vertex is (-3,3)

Part d

Find out the intercepts

y-intercept --------> (0,7)

x-intercepts ------> DNE (does not exist)
