yep confirmed

Answer 5

@Posideon can u look at this? and @TuringTest : What type of discontinuity does the function y = (x^2 - 5x) / (x^2 + 5x) have at x = 0 ?

Answer 6

take the lim as x goes to 0.

Answer 7

I got Removable discontinuity at x = 0

Answer 8

if you get a finite value then thats a removable discontinuity i think

Answer 9

you should graph it to check
