7. In some places, a suspension bridge is the only passage over a river. The height of one such bridge, h, in metres, above the

Cloud [144]

Sure. The function is a parabola. Because the coefficient of the x^2 term is positive, it opens upward. that means that it vertex is a minimum point.

You can verify that the vertex is (0,24). That means that at the point x=0, the height of the bridge is 24m. So if the level water rises below 24 m, the bridge is safe to use.
