Find a mathematical model for the verbal statement. \(y\) varies inversely as the square of \(x\)
Write a sentence using the variation terminology of this section to describe the formula. Surface area of a sphere: \(S=4 \pi r^{2}\)
Find a mathematical model representing the statement. (In each case, determine the constant of proportionality.) \(A\) varies directly as \(r^{2} .(A=9 \pi\) when \(r=3 .)\)
Determine whether the function has an inverse function. If it does, find the inverse function. $$ f(x)=|x-2|, \quad x \leq 2 $$
(a) find the inverse function of \(f\), (b) graph both \(f\) and \(f^{-1}\) on the same set of coordinate axes, (c) describe the relationship between the graphs of \(f\) and \(f^{-1}\), and (d) state the domain and range of \(f\) and \(f^{-1}\). $$ f(x)=x^{3 / 5} $$
