(1 point) Suppose that f(x) = x2 In(8 - 5x2). Find f' (x), and use interval notation to give the domain of f. Note: When entering interval notation in WeBWork, use I for co, -I for -co, and U for the union symbol. If the set is empty, enter "{}" without the quotation marks. f' (x) = (-10x^3+xin((8-5x^2)^16)-x^3In((8-5x^2)^1 Domain = (-1,(-2sqrt2)/sqrt5)U((-2sqrt2)/sqrt5,(2sqrt2)/
