Help.

For the first one.....here's a hint......expand each answer.....see if the second one leads you to

y = x^2 + 4x - 3

Is it the second choice

Correct !!!!!

For the second one.....I'll use a graph [ although I can also solve it algebraically, if you want me to ]

Look at the graph, here.....

The height of the arch is ≈ 381 ft and the length of the bridge above the arch is ≈ 1791 ft

so that would be the last answer choice

Yep...last choice.....
