Problem 1 Got It? Graph the three functions on the same plane. Zoom and pan your graph to establish an approprite viewing window. Consider the similarities and differences of the graphs. Think about domain, range, intercepts, asymptotes, etc. and how they relate to the the equation of each function.

We have released a new and improved Graphing question type! Students will no longer be able to answer this question.

Graphing:
1. Without the aid of a graphing utility, sketch a graph the equation on the canvas below using the blue ink tool.
2. Graph the equation on the embedded Desmos graphing calculator above.
3. Sketch a copy of the Demos graph on the canvas below using the red ink tool.
4. Consider any discrepancies between the graphs.
Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.
