Mathematics: DESIGN A footbridge is suspended from a parabolic support. The function h(x) = x2 + 9 represents the height in feet of the support above the walkway, where x = 0 represents the midpoint of the bridge b. What is the length of the walkway between the points where the support intersects the walkway?

If you need to substitute the equation x = y - 1.
If you have another equation, then you would plug in y - 1 into the x value of the equation you would need to substitute into.

Hope this helps
