do it all
In Exercises 65-68, use the graph of f' to (a) identify the interval(s) on which f is increasing or decreasing, and (b) estimate the value(s) of x at which f has a relative maximum or minimum. In Exercises 3-8, use the graph to estimate the open intervals on which the function is increasing or decreasing. Then find the open intervals analytically. y = x3/4 - 3x Power The formula for the power output P of a battery is P = VI - RI2, where V is the electromotive force in volts, R is the resistance in ohms, and I is the current in amperes. Find the current that corresponds to a maximum value of P in a battery for which V = 12 volts and R = 0.5 ohm. Assume that a 15-ampere fuse bounds the output in the interval 0 I 15. Could the power output be increased by replacing the 15-ampere fuse with a 20-ampere fuse? Explain. Show transcribed image text
