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. 4-78 HW eTool (Desmos). Homework Help ✎

Notice that this is a hyperbola (*y* = 1/*x*).

Notice that the vertex is (0,−5).

Notice that this is a cubic graph.

Notice that this is an exponential graph.

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

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