  1. 1-2 Composition of Functions Pre Calc A

  2. Ex 17: • Given f(x)=2x – 1 and g(x)=x² find each function: • A. (f + g)(x) • B. (f – g)(x) • C. (f · g)(x) • D. ( )(x)

  3. Ex : • For the Lotsa Coffee Shop, the revenue r(x) in dollars from selling x cups of coffee is r(x) = 1.5x. The cost c(x) for making and selling the coffee is c(x)= .2x + 110. • A. Write the profit equation P(x) • B. Find the profit for 100, 200, and 500 cups of coffee sold.

  4. Composition

  5. Ex : • Find and for f(x) = x² + 2 and g(x) = 3x

  6. Ex last one: • Find the first three iterates x1, x2, and x3, of the function f(x) = 3x + 2 for an initial value of x0 = 4
