uestion 1 of 11 The surface area S of a sphere of radius r is given by S(r) = 4xr2. Explain why, in the given context, S(r) has an inverse function. Identify the correct explanation. O S(r) is both increasing and decreasing on its domain. O S(r) is a polynomial and all polynomials are one-to-one for all real numbers. O S(r) is decreasing on its domain and therefore is one-to-one. O S(r) is increasing on its domain and therefore is one-to-one. O S(r) is linear and must have an inverse. Find the inverse of S(r), expressing r as a function of S. (Express numbers in exact form. Use symbolic notation and fractions where needed.)
