    Function:

    f (x) = x² + 3

    The domain is the maximum and minimum values of x that can be put into a function to yield another value. In this case, the domain is negative infinity to positive infinity

    D = (∞,-∞)

    The minimum value of the function is when x is 0

    The minimum value is 3

    The maximum value is ∞

    Therefore, the range is [3, ∞)

    For the function's inverse, the original domain will become the range and the original range will become the domain.
