Answer:
{x | x ≠ -1, 2, 4}
Step-by-step explanation:
Domain: input values (x-values)
Asymptote: a line which the curve gets infinitely close to, but never touches.
Hole: a point on the graph where the function is not defined.
From inspection of the graph:
- Vertical asymptotes at x = -1 and x = 4
- Hole at x = 2
As vertical asymptotes and holes restrict the domain of a rational function, the domain is {x | x ≠ -1, 2, 4}
