1.) Find f(x) and g(x) so that the function can be described as y = f(g(x)) 4/x² = + 9

2.) Confirm that F and G are inverses by showing that f(g(x)) = x and g(f(x)) = x

f(x) = x³ + 4 and g(x) = (thirdRoot x - 4)

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
