1. let f(x)=-5x-4 and g(x)=6x-7. find f(x)+g(x)
a. -11x+3
b. x+3
c. -11x-11
d. x-11

2. let f(x)=3x+2 and g(x)=6x-7. find f(x)-g(x)
a. 3x-9
b. -3x+9
c. -3x-5
d. 2x-1

3. let f(x)=-5+3 and g(x)=6x-2. find f*g and its domain
a. -30x^2+28x-6; all real numbers except x=1/3
b. -15x^2-8x-12; all real numbers except x=3/5
c. -30x^2+28x-6; all real numbers
d. -15x^2-8x-12; all real numbers

Question 1:
 We have the following functions:
 
 We have then:
 For f (x) + g (x):
 We add both functions.
 We have then:
 
 
 D. x - 11

 Question 2:
 We have the following functions:
 
 We have then:
 For f (x) - g (x):
 We subtract both functions.
 We have then:
 
 
 B. -3x + 9

 Question 3:
 We have the following functions:
 
 We have then:
 
 Rewriting we have:
 
 The domain of the function is all real because it has no restriction.
 
 C. -30x^2 + 28x - 6; all real numbers
