The following is known about three real numbers x ,y and z where x is more than or equal to -4 and less than or equal to 4 ; y is more than or equal to -8 and less than or equal to 2 and z is more than or equal to -8 and less than or equal to 2. Then the range of values that M = ( x*z )/ y can take is best represented by :

1. x is more than negative infinity and less than positive infinity
2. x is more than or equal to -16 and less than or equal to 8
3. x is more than or equal to -8 and less than or equal to 8
4. x is more than or equal to -16 and less than or equal to 16
