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!

Just help for (d), holes in the graph.
an obvious factor of 1 is present, making the function undefined for x=-4.
You did not identify the correct factor of 1 when you picked the "hole" at x=-5.
