Let's start by identifying the value of the base of the exponential function. y=7x Because the base of the function is greater than 1, we know that this is an exponential growth function. To draw a graph, we will start by making a table of values.
x | 7x | y=7x |
---|---|---|
-2 | 7-2 | 491 |
-1 | 7-1 | 71 |
0 | 70 | 1 |
1 | 71 | 7 |
The ordered pairs (-2,491), (-1,71), (0,1), and (1,7) all lie on the graph of the function. Now, we will plot and connect these points with a smooth curve.
