Consider the function r(a) = 36x⁵. + 270x⁴ + 480x³ +20. Differentiater and use the derivative to determine each of the following. All intervals on which r is increasing. If there are more than one intervals, separate them by a comma. Use open intervals and exact values. T increases on: All intervals on which r is decreasing. If there are more than one intervals, separate them by a comma. Use open intervals and exact values. r decreases on: The value(s) of x at which r has a relative maximum. If there are more than one solutions, separate them by a comma. Use exact values. r has relative maximum(s) at x = The value(s) of at which r has a relative minimum. If there are more than one solutions, separate them by a comma. Use exact values. r has relative minimum(s) at x =
