A to f equals 2.5

A to e equals 1.5

a to d equals .5

a to c equals 2

a to I equals 3.5

a to g equals 3

a to h equals 4.5

a to j equals 4

a to k equals 5.5

use the big numbers as landmarks! that's the number before the decimal ( . ) to find the number after the decimal, count the little lines!

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
