Suppose that the outer fence costs $1133 per meter and the inner fence costs $50 per meter. The total budget is $15,301:). (a) {1 point) Express the area A of the region as lVariahle function of x. (b) (1 point) Find the domain of this function. (e) {2 points} Find the maximum area of this region. (d) (1 point) ilustifj,r what you find is indeed an absolute {global} maximum of this function.
