A residual plot shows how far away each point in the scatter plot is from the least squares regression line.

The table shows two scatter plots with least squares regression lines fit to the data. Drag the residual plot that matches each scatter plot into the cell next to it.

Scatter plot one is not a good fit so answer is first picture to the left  in a top row( see the pattern). Second plot is a good fit so the answer is the last right picture in a top row( points around x axis).

Step-by-step explanation:

A random scatter of points in the residual plot indicates that the linear function is a good fit for the given data. A non random residual plot  indicates that the chosen function is not a good fit.

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
