Question

find the domain of f(x) = 3x+2/x2-5x+6​

Answer 1

Answer:

Df=R-{2,3} or Df=(-∞,2)∪(3,+∞)

Step-by-step explanation:

the  denominator must never be equal to 0

so you should solve the equaltatiob x²-5x+6=0

you wil find that the roots are x=2 or x=3 , x∈R

so the domain ca be every number except those two

so Df=R-{2,3} or Df=(-∞,2)∪(3,+∞)
