7-1 Graphing Exponential Functions Growth and Decay – it’s all in the base

From now on, you will be expected to make an EXCELLENT graph From now on, you will be expected to make an EXCELLENT graph. That means it is on graph paper (no free-hand) with scale marked, accurate points, and enough of the graph showing that the observer can see the main features of the graph (to the edge if given a grid to graph on!). It will have to be redone if not right.

Graph each function. State domain and range Graph each function. State domain and range. Make an excellent graph, with scale marked, using graph paper. 1. 𝑦= 2 𝑥
