    Hard to really give a mathematical explanation. Basically it's just that there are no points of discontinuity. No way to divide by zero, or take the square root of a negative number It doesn't switch signs or equal infinity anywhere besides infinity. It's not a piecewise function.

    Thank you. I guessed at the answer and got it right, but thought I should understand why it was right.
