Find the relative frequency of scores... a. between the mean and z = +1.40.
b. below z = -1.86.
c. above z = +2.68.
d. below z = -2.4 and above z = +1.96.

answer: (1,3) and (-2,0) i think.

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
