Which of the following best describes how the y values are changing over each interval?

x y
1 2
2 4
3 8
4 16
5 32

a) they are increasing by 2 each time.
b) they are increasing by 4 each time.
c) they are being multiplied by 2 each time.
d) they are being multiplied by 4 each time.

C) they are being multiplied by 2 each time.

Step-by-step explanation:

From the given table, we can see that the ratio between values of the y is given by :-

Therefore, the common ratio = 2, which means the y values are increasing by a multiplicative factor of 2.

Therefore, the right option is "The y values are being multiplied by 2 each time."

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
