x=1 is your discontinuity

**Eric**, Thursday, September 29, 2011 at 8:44pmWhy would it be 1?? I'm so confused...

**Brianna**, Thursday, September 29, 2011 at 8:57pmbecause having 0 in the denominator would make your function be undefined and therefore be a discontinuity at that point. If you set the denominator equal to 0 and solve your answer would be 1.

x^2+x-2=0

(1)^2 + 1 - 2=0

1+1-2=0
