Question

Hey guys would the domain is all real numbers except 3 and 4 ? Because that’s what I got.

Answer 1

Answer:

all reals except 3 & 4

Step-by-step explanation:

recall you cannot have a 0 in the denominator.  

any values of x that would produce a 0 in the denominator are excluded from the domain

factor $x^{2} -7x+12$    Factors -3, -4

                                  (x-3)(x-4)

x cannot be 3 or 4
