Question

Multiple choice: State any restrictions on the variables.

A. y ≠ 3

B. no restrictions are needed

C.y ≠ –1

D. y ≠ 1

Answer 1

I believe your answer is C. y ≠ -1. This is because if y was -1, then the denominator of the fraction would be -1 + 1 = 0, and you can't divide any value by 0.

I hope this helps!
