4. 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

5.

Solve the following logarithmic equation. Be sure to reject any value of x that is not in the domain of the original logarithmic expressions. Give the exact answer. Then, where necessary, use a calculator to obtain a decimal approximation, to two decimal places, for the solution:
