    Function Help

    Consider the function ABS(x)=/x/, the absolute value of x.

    a. What are the domain & range of ABS(x)?
    b. Find ABS(-6)

    I am not looking for the solution to this but rather what "/x/, the absolute value of x" means. I would like to try and solve it on my own and then have someone check my answer if possible. Thanks!

    ABS(x)= x if x \geq 0 and  ABS(x)=-x if x \leq 0
