12. The growth of a red oak tree is approximated by the function G(t) = -0.003t3 + 0.137t2 + 0.458t - 0.839, where G is the height of the tree in feet and t is its age in years. a. Interpret what G(10) represents with regard to this application.(State in words) b. How long will it take a red oak to reach a height of 50 feet? Use your calculator here. c. By looking at the graph of this function on your calculator decide what would be an appropriate domain and range for this function. Explain your reasoning
