Answer:
Giraffe: linear function
Sunfish: exponential function
Step-by-step explanation:
In the figure attached, the tables are shown.
Giraffe
From point to point, variation in mass is:
165 - 63 = 102
264 - 165 = 99
368 - 264 = 104
468 - 368 = 100
which is almost constant. This is a feature of a linear function (variation in moths is constant).
Sunfish
Taking logarithm of mass, we get:
0.544
1.286
2.027
2.769
3.511
From point to point, the variation in logarithm of mass is:
1.286 - 0.544 = 0.742
2.027 - 1.286 = 0.741
2.769 - 2.027 = 0.742
3.511 - 2.769 = 0.742
which is almost constant. This is a feature of an exponential function.
