You can put this solution on YOUR website!
The rational function has a critical point around which the sign changes, and this is a vertical asymptote.

The function containing the absolute value has a critical point forming a sharp corner or at least a sudden change in direction, so the function will have two branches or is built in two parts changing at t=-1.

The quadratic function will have vertex as a maximum, and you can find the roots (zeros) either by factoring or converting into vertex form (completing the square).

You must do the work!
