1. Ch. 7 Day 6 Book Section 7.6 Function Operations

2. (f+g)(x) = ____________________ (f-g)(x) = ____________________ (f  g)(x) = ____________________ __ ____________________________ (f+g)(x) = ____________________ (f-g)(x) = ____________________ (f  g)(x) = ____________________ f(x) + g(x) f(x) – g(x) f(x)  g(x) g(f(x))

3. Given f(x) = and g(x) = Find (f-g)(x) = ____________________ Domain Restrictions: Ex 1 Find (f-g)(2) = ____________________ Sub 2 for x !

4. Given f(x) = and g(x) = Find (fg)(x) = ____________________ Domain Restrictions: Ex 2 Find (fg)(-3) = ____________________ Sub -3 for x !

5. Given f(x) = and g(x) = Find (f/g)(x) = ____________________ Domain Restrictions: Ex 3 Find (f/g)(0) = ____________________ Sub 0 for x !

6. Given f(x) = and g(x) = Find f(g(x)) = ____________________ Domain Restrictions: Ex 4 Find (f◦g)(2) = ____________________ Sub 2 for x !

7. Given f(x) = and g(x) = Find f(g(x)) = ____________________ Ex 5 f(x) and g(x) _____ inverse functions because f(x) = g(x) = ___ Find g(f(x)) = ____________________

8. Given f(x) and g(x) = Find f(f(x)) = ____________________ Domain Restrictions: Ex 6 Find (f◦f)(3) = ____________________ Sub 3 for x !
