Use the line to approximate the rate of change for the parabola between x = 1 and x = 2.

A) 1
B) 2
C) 3
D) 4

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

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
