Question

The graph to the right shows the projected elderly population of a country for ages 65-84 and for ages 85 and older. The function $f(x) = 6\sqrt{x} + 33.2$ models the projected number of citizens ages 65-84, $f(x)$, in millions, $x$ years after 2010. Complete parts (a) and (b). a. Use the function to find $f(40) - f(10)$. Express this difference in simplified radical form. What does this simplified radical represent? $f(40) - f(10) = \boxed{}$ (Type an exact answer, using radicals as needed.)
