4-78.

Write a possible equation for each of these graphs. Assume that one mark on each axis is one unit. When you are in class, check your equations on a graphing calculator and compare your results with your teammates.

1. Notice that this is a hyperbola $(y=\frac{1}{x})$.

1. Notice that the vertex is $(0,−5)$.

1. Notice that this is a cubic graph.

1. Notice that this is an exponential graph.

1. Notice that the $y$-intercept is $(0,−6)$.

1. See the hints from parts (a)-(e) to help you solve parts (f)-(i).

Use the eTool below to graph the equations.
