To find the domain of the function, we can solve for the zero of the denominator. The numbers that can’t be included are the ones that make the denominator equal zero.

x - 3 = 0

x - 3 + 3 = 0 + 3

x = 3

Therefore, the domain is all real numbers except 3.

Best of Luck!

Answer:

The domain is all real numbers except x=3

Explanation:

Assuming you mean

f(x) = 1/(x-3)

The domain is all numbers that x can take

This function is define except when the denominator goes to zero

x-3 cannot be zero

x cannot be 3

The domain is all real numbers except x=3
