what is the equation for the axis of symmetry? there is an equation, which may be -b/2a, but I'm not sure
but i have the graph of -x^2+9 and another graph after a translation of 7,0
thanks!

-x^2+9
This is basically the graph of x^2, flipped on the x-axis and moved up 9 units. Because you have no horizontal translation (left or right), the axis of symmetry would still be at x=0.
If you had a translation of 7 units to the right, your axis of symmetry will also move 7 units to the right, so your new axis is when x=7.

-b/2a is right, but this equation is to get the x coordinate of the vertex of a parabola. hope this helps
