Question

Which group of values makes the expression 3x2y−2z UNDEFINED? A) x = –1; y = 0; z = 3 B) x = –1; y = 3; z = 0 C) x = 0; y = −1; z = 3 D) x = 0; y = 3; z = −1 E) x = –1; y = 2; z = 1

Answer 1

the correct question is
Which group of values makes the expression 3x/2y−2z UNDEFINED?

we know that
So that the expression is defined, the denominator in (3x/2y) can not be zero
hence 
the value of y = 0 makes the expression UNDEFINED

therefore

the answer is
the option A) x = –1; y = 0; z = 3
