CPM Homework Help : PC3 Problem 6-51

Graph each of the following functions and state the domain of each function.

Hint:

The domain is all of the possible $x$ -values for which an output of the function exists. Consider values where $x$ causes division by zero or a negative number inside an even root.

$f\left(x\right)=\frac{5}{x+2}$

$g\left(x\right)=\sqrt{3-x}$

$h\left(x\right)=\frac{1}{x^2-1}$

$j(x)=5x^3+7$
