Find the horizontal asymptote as x --> 8 and then describe what this means in practical terms. F(x) = 150x + 120/0.05x + 1; the number of bass, f(x), after x months in a lake that was stocked with 120 bass.

the number of bass, f(x), after y months in a lake that was stocked with 130 bass
the number of bass, f(x), after x months in a lake that was stocked with 120 bass
the number of bass, f(x), after x months in a lake that was stocked with 140 bass
the number of bass, f(x), after x months in a lake that was stocked with 150 bass

None of the choices are correct unless you meant:

F(x) = (150x + 120)/(0.05x + 1)
then ....
f(0) = (0+120)/(0+1) = 120

so it was initially stocked with 120 bass

and the limit as x→∞ is 120/0.5 = 240
