really need help.
f(m) = -2 / (-3+9m)
how to find range on this?
and how to find range on
f(w) = 7 / ( -2 + |w| )
sorry, need to know how you did it!

Use WA to sketch graphs of the functions.
For the first one this is a graph ,so you can conclude that range is :
$\displaystyle y \in (-\infty , +\infty) \backslash \{0\}$
Brake second function in two cases and sketch graphs for the each one separately .
