Question

what's the limit of lim (x-5)/(x^2 -25)
x-> 5+

Answer 1

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

Answer 2

is positive infinity wrong?

Answer 3

It is, the limit is 1/10

Answer 4

but when you graph it, the line approaching x=5 never ends....

Answer 5

well I did not graph anything just used algebra
