Solution by Steps
step 2
From the graph, observe that at x=5x = -5, there is an open circle, indicating a removable discontinuity
step 3
At x=1x = 1 and x=5x = 5, there are vertical dashed lines, indicating vertical asymptotes, not removable discontinuities
step 4
Therefore, the only removable discontinuity is at x=5x = -5
A
Key Concept
Removable Discontinuity
Explanation
A removable discontinuity occurs at a point where a function is not defined, but the limit exists. In this case, the open circle at x=5x = -5 indicates such a discontinuity.
