Define a variable , write an inequality , and solve the problem: The difference of a number and 4 is no more than 8

Please help!

= smallest number and = biggest number, so

Explanation:

The difference from , so s = -4 and b = 4.

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

i think it is c, not positive though
