college algebra

arithmetic combinations .. find

a. (f+g) (x)

b. (f-g) (x)

c. (f*g) (x)

d. (f/g) (x)

what is the domain of f/g

 

1. f (x) = 2x-5, g(x)=-x

2. f(x)= 3x+1, g(x)=5x-4

f(x)= 2x-5

g(x)= -x

 

first find f/g=f(x)/g(x)

                =2x-5/-x

 

Equate the denominator=0 to find the domain.

-x=0 implies x=0.

 

so domain is set of all real values except at x=0.

 

question 2:

f(x)=3x+1 g(x)=5x-4

 

f/g=3x+1/5x-4

to find domain equate denominator to zero.

5x-4=0

simplify

5x=4

x=4/5

so domain has all real values except at x= 4/5. cheers.
