When you look at a fish in a still stream from the bank, the fish appears shallower than it really is due to refraction. From directly above, it appears When you look at a fish in a still stream from the bank, the fish appears shallower than it really is due to refraction. From directly above, it appears: a. shallower than its real depth.
b. deeper than it really is.
c. at its actual depth.
d. It depends on your height above the water.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
