MULTIPLE CHOICE QUESTION

Student 1 says that the restrictions of 9(d4)(d7)(d+8)\frac{9\left(d-4\right)}{\left(d-7\right)\left(d+8\right)} are d4d\ne4 , d7d\ne7 , and d8d\ne-8 . Is Student 1 correct? Why?

Yes because d = 4, d = 7, and d = -8 all make the denominator equal to zero

Yes because d = 4, d = 7, and d = -8 all make the expression evaluate to zero

No because d = 4 does not make the denominator equal to zero

No because the real restrictions are d4d\ne-4 , d7d\ne-7 , and d8d\ne8

No because d = 0 is also a restriction
