If f(x) = 1x−3 , what is the domain of f(x)?

Question

Solving for the domain, take note that division by zero is undefined. From the given equation, x-3 must not be equal to zero and must not be included into the domain. Therefore the domain of f(x) are all real number except x = 3

Answer 1

wotcha meen x=0 prohibited????

simpel subtrakt, so raenj=domaen=all reel numbers,

unless teech wanna get intu komplex numbers
