OpenStudy (anonymous):
x^2-25=(x+5)(x-5) so you can cancel x-5 this will remain: lim 1/(x+5)=1/(5+5)=1/10
OpenStudy (anonymous):
is positive infinity wrong?
OpenStudy (anonymous):
It is, the limit is 1/10
OpenStudy (anonymous):
but when you graph it, the line approaching x=5 never ends....
OpenStudy (anonymous):
well I did not graph anything just used algebra
