Leonard is studying the relationship between the fuel efficiency in miles per gallon (mp3), y, and the speed in miles per hour (mph), x, of his car. He collected data for
8 different speeds and found a linear model that best fit his data: y = 18.46+0.16%. To analyze the fit of his function, he found the residuals and created the following
residual plot.

the forst and 3rd

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
