To determine whether or not grade level influences time spent studying

We have to determine the response variable.

Response Variable:

For the given survey:

Response variable:

Time spent studying

Independent variable:

Grade level

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

its (2) option

is means division by fractions
