Answer: -101
Step-by-step explanation: f(n) = 19-6*n
f(20) = 19 - 6*20
f(20) = -101
We have the following table:
Round Number of Strokes Above or Below 72
1 -5
2 +6
3 -2
4 -4
5 +5
So, the expression that represents the total number of strokes is:
72 + (Number of strokes Above or below 72)
Therefore, for every round we get:
Round Number of Strokes Above or Below 72 Total number of strokes
1 -5 72 - 5 = 67
2 +6 72 + 6 = 78
3 -2 72 - 2 = 70
4 -4 72 - 4 = 68
5 +5 72 + 5 = 77
The total number of strokes is:
67 + 78 + 70 + 68 + 77 = 360
Additionally, the average is the total number of strokes divided by the number of rounds, so it is equal to:

Answer: Total: 360 Strokes
Average: 72 Strokes
Step-by-step explanation:
Gradient of line AB = 6/2 = 3.
Gradient of line CD = 10/2 = 5.
Gradient of line AD = 12/8 = 1.5.
The graph displays y = -2x + 1
So, f(-1) would be:
f(-1) = -2(-1) + 1
= 2 + 1
f(-1) = 3
