    \[\large\rm |x-3|=\cases{(x-3),\qquad x\ge3\\ \rm -(x-3),\quad x\lt3}\]

    So when we're on the `left side of 3`, Our |x-3| is -(x-3), giving us a function of:\[\large\rm t(x)=2^x-\frac{-(x-3)}{(x-3)}\]Err I guess it would be better to do this with limits. Approach 3 from the left, and seperately approach 3 from the right and see if the two pieces connect. If they don't, we have a jump discontinuity.

    \[\large\rm \lim_{x\to3^-}t(x)=2^{x}-\frac{-(x-3)}{(x-3)}\]Do a cancellation before plugging the 3 in :)

    Yes. I said it was a jump discontinuity. I just needed a starting point.
