Step-by-step explanation:

For each of the following functions, using separate sheets find :

a. the general formula for f +g, f-g, and f/g

b. the value of each at x=3 and x=-2

c. the domain of each combination by using the definition

1.f(x)=4x-5 and g(x)=5-2x

2. f(x)=x-3x and g(x)=x2-3x

3. f(x)=9-x2 and g(x)=√ 5-2x

4.f(x)= 2x and g(x)=x2 +3x+2

5. f(x)=3x-4 and g(x)= √x2-4x+3
