Question 972885: Consider the function
Using algebra only (not a graphing calculator), find the following features of the graph.
a) x-intercept(s)
b) vertical asymptote(s)
c) horizontal asymptote(s)
d) removable discontinuity (“hole”)
I already found a-c, I just need help with d. I had said that x+5=0 so x=-5, therefore the domain is all real #'s but -5, but that was wrong. Please help, thank you! Answer by josgarithmetic(39617) (Show Source):
