For this case we have the following equations:

We must find 
By definition of composition of functions we have to:

So:

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

So, the roots are:

The domain is given by all real numbers except 0 and 3.
Answer:
x other than 0 and 3
Answer:
Quadrant 1 is the top right side. Quadrant 2 is top left. Quuadrant 3 is bottom left. Quadrant 4 is bottom right.
Step-by-step explanation:
<h3>
You must mark the number on the quadrants starting by the middle is the axis (0). Then you count from 1 to how ever much the quadrants end. There the y axis and the x. Those are the lines that seperate the 4 quadrants. Quadrant 1 is both postive #. quadrant 2 is a negative number and a postive. depending on how the x and y are. the X axis is spostive the y is negative. Point A is (10,4) and its quadrant is 4. You must count all the boxes which go all the way up to 10. You must start in the center then either go up for Y or down. Go right or left for X. B is -8,9</h3><h3>
