Best Fit Curves 100

Which type of regression fits the data? Explain.

x 16 17 18 19 20

y 8 6.5 5 7 12.3


Answer

Quadratic regression because as the x values

increase the y values decrease and then begin to

increase.


Best Fit Curves 200

Based on the graph provided, what do you know about the value of “a”?


Answer

The value of “a” is negative because the graph opens

down.The absolute value of “a” is

between 0 and 1 because the graph is wider than the parent

function.
