Clearly show all steps for each problem. 1) Given the function f (x) = x + 2 , following the 5 steps for \"Finding Absolute Extrema on a Closed x Interval\" found in Section 12.5 of the textbook (or 3.5 in the printed version), find the exact absolute maximum and minimum values of the function on the interval [1,10]. Clearly label each of the 5 steps. 2) A rectangular lot that borders a river is to be fenced with two types of fencing. The side that borders the river will not be fenced. The side opposite the river will be fenced with material costing $1.50 per foot, and the other dimension will be fenced with material costing $2.50 per foot. See the diagram below. river $2.50/ft $2.50/ft $1.50/ft Use calculus techniques to nd the maximum area that can be fenced for $9300 m the dimensions of the lot that maximize the area. Clearly show your work, which should include a well-labeled sketch
