Question

Determine weather the following table represents an exponential function. EASY!!!!!!!!!!!!!!

Answer 1

Answer:

A

Step-by-step explanation:

Rate of change for x is constant:

1-0 = 1

2-1 = 1

3-2 = 1

it's all the same so it's constant.

Ratio of y is not constant:

12/8 ≠ 24/12 ≠ 52/24

I'm guessing it's A. Previous answer was my bad

Answer 2

Answer: Choice A) No. All of the x values have a constant difference, but the y values do not have a constant ratio.

Explanation:

The x values increase by 1 each time. So the constant difference is 1. We can see this by subtracting adjacent values such as 4-3 = 1 or 5-4 = 1 and so on.

The y values do not have the same constant ratio. Divide each y term by its previous value

12/8 = 1.5

24/12 = 2 ... we can stop here but I'll keep going to list all the ratios

52/24 = 2.167 approximately

We get different results each time we divide the y values. So this shows we do not have an exponential function.
