Answer:
lim f(x)=(11x-40)/(x-4) // for all x's, except x=4
lim f(x) ≈ ∞ // if x=4
Step-by-step explanation:
lim f(x) - 4/(x - 4) = 11
lim f(x) = 11 + 4/(x - 4)= (11x-40)/(x-4)
at x=4, there is a indetermination point, the function tends to infinity at that point
So:
lim f(x)=(11x-40)/(x-4) // for all x's, except x=4
lim f(x) ≈ ∞ // if x=4
