Question

The table shows the weight of an animal, in kilograms, over a period of several months, with a question mark for a missing weight. Use the table to solve a problem involving function models. Which statement is true?


The situation is modeled by a linear function with equal differences of 15.5.

The situation is modeled by a linear function with equal differences of 19.5.

The situation is modeled by an exponential function with equal factors of about 0.25.

The situation is modeled by an exponential function with equal factors of about 1.25.

Answer 1

I don't think it's A or B.

Answer 3

@perl

Answer 4

you're right, it cannot be linear

Answer 5

take the ratio of consecutive terms for finding the multiplication factor

Answer 6

\[\dfrac{78}{62.5} = ?\]

(notice the model was scaled for units as 3 months on x axis)

Answer 7

@ganeshie8 D?

Answer 8

Yep!
