Consider the following function. f(x} = (x + (5)2, x 2: 6 Find the inverse function f'l. f1(x) = E State the domain and range of 1'. (Enter your answers using interval notation.) domain range UH State the domain and range of f'l. (Enter your answers using interval notation.) domain range UH Find a mathematical model that represents the statement. (Determine the constant of proportionality.) z varies directly as the square of x and inversely as y. (z = 8 when x = 8 and y = 6.)
