Answer:

Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.

( g o f ) = ( 7 x + 1 ) − 1 7 this will result in (gof)=x ( f o g) = 7 x − 1 7 +1 = x − 1 + 1 =x

graphically you can check this if it seems that the functions are reflected over the line x=y.

<em>In the next year, Anthony worked 2,084 hours</em>

Step-by-step explanation:

Anthony worked 1,697 hours in 2010.

We also know Anthony worked 22.8% more hours than in 2010.

The problem requires to calculate how much did Anthony work in the next year.

It can be calculated as follows:

Take 22.8% of 1,697:

$22.8 * 1,697 / 100 = 386.916\approx 387\ hours$

Now calculate by adding it to the original number of hours:

1,697 + 387 = 2,084 hours

In the next year, Anthony worked 2,084 hours
