If f(x)=2x+3, find the following

1) f(4)

2) f(-2)

Given the following tales

x y

1 4

4 8

7 20

12 24

14 28

16 30

What is the domain?

What is the range?

Do a linear regressionand tell the values of a, b, r2, and r and tell if the correlationis positive or negative.

Hi there,

Thanks for letting me work on your post. Here is my explanation:

1) f(4)=2*4+3=11; f(-2)=2*(-2)+3=-1

2) The domain is the value of x and therefore, the domain is 1, 4, 7, 12, 14 and …

This solution provides a detailed, step-by-step explanation of the given statistics problem.
