To plot the function $y = 3^x - 2$, you can choose some values for $x$ and compute the corresponding values for $y$. Here are a few points to get you started:

$x$	$y = 3^x - 2$
-2	$3^{-2} - 2 = \frac{1}{9} - 2 \approx -1.888$
-1	$3^{-1} - 2 = \frac{1}{3} - 2 \approx -1.667$
0	$3^0 - 2 = 1 - 2 = -1$
1	$3^1 - 2 = 3 - 2 = 1$
2	$3^2 - 2 = 9 - 2 = 7$
3	$3^3 - 2 = 27 - 2 = 25$
4	$3^4 - 2 = 81 - 2 = 79$

These points should give you a good curve to plot.

Here are a few related questions you might find interesting:

1. What are the general properties of exponential functions like $y = 3^x - 2$?
2. How does shifting the graph of $y = 3^x$ affect its shape?
3. What is the behavior of $y = 3^x - 2$ as $x$ approaches positive or negative infinity?
4. How do you find the horizontal asymptote of an exponential function?
5. Can you compare the graph of $y = 3^x - 2$ with $y = 2^x - 2$?

Tip: To quickly plot exponential functions, pick several integer values of $x$ and compute the corresponding $y$-values. For smoother curves, you can also use fractional $x$-values.
