Question

Please, I need help only with these 3 questions.

Answer 1

for the first one, think, what number can you put in x to make it undefined. Remember when we have 0 on the bottom we can't divide thus it means it is undefined. So zero times any number equals zero. Meaning the answer 0 is correct because when u multiply it you can't divide by zero

Answer 2

Exactly what I was thinking. I needed to make sure on the first one in case I don't get the explanation wrong because 0= undefined. Thanks.

Answer 3

and with the second one, because u have choices, you can plug it in for x and keep trying until u get 5
