What is the domain of the function f (x) = 1 / (x-3) ?

F (x) = 4x-5 hope this is right

Domain means the numbers you can use (basically, all real numbers except for those that make undefined stuff, like dividing by zero or having square root of negative)

ok so

1 / (x-3)

no sqare roots so

find what numbers make divion by 0

1 / (x-3)

1/0=1 / (x-3)

0=x-3

3=x

3 makes a division by 0

3 is not allowed

domain is all real numbers except for 0
