Prove the statement using the E, Delta definition of a limit. Lim(as X approaches -1.5) (9- 4X ^2)/(3+2x)=6
the answer is delta=e/2 not -e/2. Remember delta must be positive !!
in the final steps, you will find |2x+3|<e, factorize by 2 to get 2|x+1.5|<e, then rewrite 2|x-(-1,5)|<e finally divide both side by 2 to find |x-(-1,5)|< e/2
