Find g(0). d). Estimate -2). e). mate the solutions to g(x0 0. f). Estimate the values of x for which f(x) 3. g). For which value(s) of x is f(x) g(x). h). Find the values of x forwhich f (x) g(x). i). Estimate f Cg(1)]. 2). Using the graph at the right, answer the following. a). Find f(2). b). Estimate g(2). c). Find the value for x such that g(x) 32. d). Estimate the value(s) for x such that f(x) 2. e). For which value(s) of x is f(x) g(x) f). For which values of x is f (x) g(x) g). For which values of x is g(x) 2 f (x) h). Find the solution(s) to f(x) 1. f(x) g(x) f(x) g(x)

Solution

1. a. f(-5)=0

b. f(0)=3.5

c. g(0)=0

d. g(-2)=-1

e. g(x)=0

x=0,-1.5

f. f(x)=3

x=1

g.f(x)=g(x)

x=1, x=-3

h. f(x)>=g(x)

[-3,1]

i. f(g(x))=f(3)=2.1
