    Domain ~ x values
    Range ~ y values

    You have to work the function and figure them out.

  2. The domain is the limits of the x values.
    The range is the limits of the y values.

    domain is the values for the function in terms of x for which the function can be defined….. for example if f(x) = 1/x we say the domain of this function is R-{0} as f(0) is not defined…..
    now range is the values we get if we giv some in put….. for example for the same above function, if we take f(2) the result is 1/2 we say the range is 1/2 for x=2… here we can define range as R-{0} as we cannot hav f(x) = 0

  4. domain is the limit of the x values
    range is the limit of the y values

    domain=x-intercept
    range=y-intercept
