Unformatted text preview: 2 8 on [-4,2] Find the absolute max and absolute min of f(x) = 3x 4- 4 x 3 +4 on [-1,5] Find the absolute max and absolute min of f(x) = 7x 2 + 7 x 5 If f(x) = 1/ (x 2 + 4), Then f(x) =- 2x/( x 2 + 4) 2 . Find the absolute maximum Find the absolute minimum If f(x) = x/ (x 2 + 4) on [-1,4], , Then f(x) = - (x-2)(x+2)/( x2 + 4) 2 . Find the absolute maximum Find the absolute minimum A watch company is marketing a new high-end watch. The demand function is given by p= 360 (1/3)x for 0< x< 20, Where p is the price in dollars and x is the number of units sold at price p. The cost function for producing x units per day is C(x) = 100 + 216x. Therefore, the profit function is P(x) = 144x (1/3)x 3 100. How many watches should be produced each day to maximize profit?...
