Help is needed! Is f(x) a function?

False

Step-by-step explanation:

This is not a function

The same x value goes to 2 different y values

5 goes to both 2 and 1

This is not a 1 to 1 correspondence

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
