Find the domain, range, and zeros of the function? HELP
When you are asked for the domain, you are to identify where a function exists with respect to the x-axis. As the x-axis is the horizontal axis (left to right), you would want to note the arrows on either end of the parabola.

Composite Functions involving Rational Functions?
I am supposed to find f-g, f/g, fog, and gof and state the domain of each for this problem but I don't know how to do it because it is a rational function. This is what it looks like: f(x)= x+1/2x-3 and g(x)= 3-x/4x+1. Any help would be much appreciated!
