"A bridge is to be constructed across a river that is 200 feet wide. The arch of the bridge is to be semielliptical and must be constructed so that a ship 40 feet wide and 30 feet high can pass safely through the arch with a horizontal clearance of 5 foot on each side. Find the equation for the arch and approximate the height of the arch in the middle of the bridge."

I'm in 8th grade, and I'm not entirely sure what an exponential relationship is. In class, we're doing exponential growth and decay, so we have to identify if a specific problem describes an exponential relationship.

Could you give me an example with this problem?:

1a. y = 100 * 3^x

So how can you identify an exponential relationship? Does it mean if the problem includes exponents?

Thanks!
