___ ____

4. Given f(x)=x-6 and g(x)=x-3, find ((f-g)(x)

5. Graph function and find the y-intercept; f(x)=0.8x+5

6. Which is the difference quotient of the function: f(x)=x-4

7. Find the difference quotient of the function:f(x)=-x squared -5x+4

8. If f(x)=4-x squared and g(x)=2-x, find (f+g)(x).

9. Given f(x)=3x squared-3,find the value of x which gives f(x)=24
