The function is given as

f(x)=4\cos (\pi x)+1

For the equation of mid-line ,

From the function, we have a vertical shift up 1.

So the mid-line is y=1.

Maximum -

The amplitude of the function is 4.

From 1, you can go up 4 values to find the maximum.

Therefore, the maximum is 1+4=5

Minimum-

The amplitude of the function is 4.

From 1, you can go down 4 values to find the minimum.

Therefore, the minimum is 1-4=-3.

It took 3 days to complete a work by 10 people.

         

<h3>What is Efficiency?</h3>

The efficiency is the output of the work which we divide by the work input and then express it in a percentage form.

Here, Efficiency of 1 person to complete a piece of work in 30 days is 1/30.

The number of days to complete the work = n days

Number of person to complete the work = p.

Now, according to question

Number of days to complete the work by 10 people = 30 / 10

                                                                                      = 3 days.

Thus, it took 3 days to complete a work by 10 people.
