Question

What is the exponential regression equation that fits these data?

Answer 1

Answer:

C.) 3.80*2.01^x

Step-by-step explanation:

Given the data :

-4 - - - -> 0.25

-3 - - - -> 0.5

-2 - - - - > 0.9

-1 - - - - - > 1.9

0 - - - - - -> 3

1 - - - - - - > 7

2 - - - - - > 18

3 - - - - -> 30

4 - - - - - > 68

The exponential regression equation is expressed in the form:

y = a * b^x

Where a = Initial value or value on the y-intercept

b = constant value

x = input value

Using the online exponential regression calculator :

y = 3.80 * 2.01^x
