Bella recorded data and used her graphing calculator to find the
equation for the line of best fit. She
then used the correlation coefficient
to determine the strength of the
linear fit. Which correlation
coefficient represents the strongest
linear relationship? Justify
1) 09 3)-0.3
2) 0.5 4)-0.8

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
