Which number is a solution of the inequality? b > 2.1 a. –12 b. 5 c. 1 d. –8

5 ¯\_(ツ)_/¯

Step-by-step explanation:

When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to".

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

the answer will be
