Question

Which function has a removable discontinuity?
a.) h(x)= (x^2-x+2)/(x+1)
b.) f(x)= (5x)/(1-x^2)
c.) g(x)= (2x-1)/(x)
d.) p(x)= (x-2)/(x^2-x-2)

Answer 1

Can someone please help?

Answer 3

yay thank you :D

Answer 4

if you have factors on the top and bottom that cancel, then this is a removable discontinuity. You can find the y-value of the discontinuity by cancelling the common factors, and then plugging in the x-value of the hole to what's left

In other words, a removable discontinuity looks like 0/0
a non-removable discontinuity looks like 1 / 0
