(a) Determine the interval where the function f(x)= v4- 2x is increasing/decreasing. (b) Let the demand function be given by p = f(z) = (x +5)², where z is the number of units of a certain commodity, 0SIS 10, and p is its price in dollars. Find the revenue function and calculate the marginal revenue when the level of sales is at 5 units.
