1. SECTION 1.5: COMBINATIONS OF FUNCTIONS

2. TARGET 1C: EVALUATE AND PERFORM OPERATIONS WITH FUNCTION NOTATION.

3. Combinations of Functions: Just as with two real numbers where we can use operations such as addition, subtraction, multiplication and division; we can do the same with functions.

5. Let f and g be distinct functions, then:

6. EX 2: Let and a.Find and then evaluate at x = 2 b.Find and then evaluate at x = 2

7. EX 3: Let and a.Find and then evaluate at x = 4 b.Find and state the domain.

8. EX 4: Let and Find,, and. Then evaluate all the composite functions at x = 3 and state the domain for.
