Question

During the first four months of employment, the monthly sales S (in thousands of dollars) for a new salesperson depend on the number of hours x of training, as follows:

S= S(x)= 9/x+10+x/4, x>=4

(a) Find lim x→4^{−} s(x)

(b) Find lim x→10 s(x)

Step 1

Part (a)

S= S(x)= 9 / x + 10 + x / 4, x ≥ 4

The given function is defined only for x ≥ 4. We don't have the branch of...
