Question
complete the table for the function $y = 5^x$.
| $x$ | $y$ |
|---|---|
| $0$ | $square$ |
| $1$ | $square$ |
| $2$ | $square$ |
now, graph the function.
plot two points to graph the function.
graph with x-axis from -8 to 8 and y-axis from -6 to 8, grid lines, and origin at (0,0)
Step1: Calculate y when x=-1
Use negative exponent rule: $y=5^{-1}=\frac{1}{5}=0.2$
Step2: Calculate y when x=0
Use zero exponent rule: $y=5^{0}=1$
Step3: Calculate y when x=1
Substitute x=1: $y=5^{1}=5$
Step4: Calculate y when x=2
Substitute x=2: $y=5^{2}=25$
Step5: Identify points for graph
We can use the points $(0, 1)$ and $(1, 5)$ (or any two from the completed table) to plot the exponential function.

Completed Table:
| $x$ | $y$ |
|---|---|
| 0 | $1$ |
| 1 | $5$ |
| 2 | $25$ |
Graph Points:
Plot the points $(0, 1)$ and $(1, 5)$ on the coordinate grid, then draw a smooth increasing curve through them that approaches the x-axis as $x$ decreases to negative infinity.
