1.find the inverse of f(x)=4x2 for x >/ 0.

The inverse function is f-1(x)=

2.The monthly profit from producing and selling x units of a product is given by the formula below.

p(x)= - 0.2x2 + 500x - 200,000

producing and selling how many units will result in a profit for this product?

use an interval to describe how many units can be produced and sold to produce a profit.

3.The total revenue function for a certain product is given by R=560x dollars, and the total cost function for this product is C= 20,000 + 40x + x2 dollars, where x is the number of units of the product that are produced and sold.

a. find the profit function.

b.find the number of units that gives maximum profit.

c. Find the maximum possible profit.

a. P(x) =

b. Th number of units that gives maximum profit is x =

c.The maximum possible profit is $

4.if f(x) = x2 - 4x and g(x) = 9 - x3 , evaluate the fallowing.

a.(f+g)(1) =

b.(g - f) (3) =

c.(f * g)(-1)=

d.(g/f) (-3) =
