Question

find the domain of f(x)=tan(x)-3

Answer 1

Domain deals with the x value and range with f(x). To determine the domain you need to ask yourself is there any value that x cannot be?

Answer 2

Do you know how the tan(x) graph looks in radians?

Answer 3

The red lines are asymptotes, values that x can't be in tan(x)

Answer 4

That would be the range though..not the domain.

Answer 5

thank you
