Ответ:
we will proceed to resolve each case to determine the solution
we have
we know that
if the value of x is the solution of the inequality, then x must satisfy the inequality.
case a)
substitute the value of x in the inequality
> is not true
therefore
the value is not a solution for the inequality
case b)
substitute the value of x in the inequality
> is not true
therefore
the value is not a solution for the inequality
case c)
substitute the value of x in the inequality
> is true
therefore
the value is a solution for the inequality
case d)
substitute the value of x in the inequality
> is not true
therefore
the value is not a solution for the inequality
case e)
