How can Kendra determine if the function is actually linear?

D. she can check to see if the rate of change between the first two ordered pairs is the same as the rate of change between the first and last ordered pairs

Yeah it is correct

Step-by-step explanation:

you have already given your answer in the question!

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
