Question

What is the domain for the following function?

y=2x/x-3

A. {x≠0}
B. {x≠-3}
C. {x≠3}
D. {all real numbers}

Answer 1

You can't divide by zero. So x-3 can't equal zero. So this means that x can't equal zero. So the answer is choice C

Answer 2

oops I meant x can't equal 3 (since x-3=3-3=0)

Answer 3

thank you!
