To create a table of coordinates for the function \( f(x) = 3^x \), we will calculate the value of the function for each designated \( x \) value. Here's how you can do it for the provided \( x \) values: -2, -1, 0, 1, 2.

  1. For \( x = -2 \): \[ f(-2) = 3^{-2} = \frac{1}{3^2} = \frac{1}{9} \]

  2. For \( x = -1 \): \[ f(-1) = 3^{-1} = \frac{1}{3} \]

  3. For \( x = 0 \): \[ f(0) = 3^0 = 1 \]

  4. For \( x = 1 \): \[ f(1) = 3^1 = 3 \]

  5. For \( x = 2 \): \[ f(2) = 3^2 = 9 \]

Now we can fill out the table:

| \( x \) | \( y = f(x) \) | |:-----------:|:------------------:| | -2 | \( \frac{1}{9} \) | | -1 | \( \frac{1}{3} \) | | 0 | \( 1 \) | | 1 | \( 3 \) | | 2 | \( 9 \) |

Summary of the Coordinates:

  • \( (-2, \frac{1}{9}) \)
  • \( (-1, \frac{1}{3}) \)
  • \( (0, 1) \)
  • \( (1, 3) \)
  • \( (2, 9) \)

You can now use these calculations to plot the function on a graph!
