If y equals ((x plus 1) times (x minus 2)) over ((x plus 3) times (x minus 4)), for which of the following values of x is y NOT defined?

Answer Choices

Answer

Division by 0 is not defined, so y equals ((x plus1) times (x minus 2)) over ((x plus 3) times (x minus 4)) is not defined when (x plus 3) times (x minus 4) equals 0. The product (x plus 3) times (x minus 4) is equal to 0 if x equals negative 3 or if x equals 4. Therefore, y is defined for all of the choices except negative 3.
