Let and g be the functions given by f(x) = x^2 and g(x) = x|x|.

 

a. f(1/3) = 

 

b. g(4) = 

 

c. g(–√3)

 

d. What is the domain of f?

 

e. What is the range of g?

 

f. Evaluate f(-67) + g(-67)

a       f (1/3)  = (1/3)^2   = 1/9

 

b       g (4)  = 4  l 4 l   =  4 * 4  = 16

 

c       g ( -√3)  = (-√3) l -√3 l  =  ( -√3 ) √3  =  - √9   =  -3

 

d   The domain is all real  numbers

 

The range is all real numbers

 

f    f(-67)  + g(-67)   =   

 

 (-67)^2  +  -67 l -67 l    =

 

67^2  - 67 (67)  =

 

67^2  - 67^2   =
