In order for a function to have an inverse that is also a function there are 2 main requirements:

1. The function should be bijective (ie) the function should be one-one ( each element in codomain has not more than 1 pre image in domain) and onto ( Range should be equal to codomain)

2. The inverse function should be defined by a suitable domain and range

Step-by-step explanation:

Let x represent the least number of points per day of golf.

This means that his least score for 2 days would be 2x

Jesse played two days of golf. On the second day he got a score of 2 below par or -2. This means that his score on the second day would be

x - 2

His total score for the two days was 8 below par or -8. This means that the total score would be

2x - 8

The score on the first day would be the total score - the score on the second day. It becomes

2x - 8 - (x - 2) = 2x - 8 - x + 2

= 2x - x + 2 - 8

= x - 6

His score on the first day was 6 below par or - 6
