Hello i still have a problem about graphing absolute values:

Sketch the graph of the function and find the indicated limit if it exists; if the limit does not exist, state the reason:

$\displaystyle G(x) = |2x - 3| - 4$

find:

$\displaystyle a.) \lim_{x \to {\frac{3}{2}}^+}$

$\displaystyle b.) \lim_{x \to {\frac{3}{2}}^-}$

$\displaystyle c.) \lim_{x \to {\frac{3}{2}}}$<--- does it exist?

Thanks and

Happy holidays!
