1 answer

To complete the table for the function \( y = 9^x \), we will calculate the values of \( y \) for each given value of \( x \):

  1. For \( x = -1 \): \[ y = 9^{-1} = \frac{1}{9} \approx 0.1111 \]

  2. For \( x = 0 \): \[ y = 9^0 = 1 \]

  3. For \( x = 1 \): \[ y = 9^1 = 9 \]

  4. For \( x = 2 \): \[ y = 9^2 = 81 \]

Now, we can complete the table:

| \( x \) | \( y \) | |---------|------------| | -1 | 0.1111 | | 0 | 1 | | 1 | 9 | | 2 | 81 |

Two Points to Graph the Function

From the table, we can choose the following two points to graph the function:

  1. \( (0, 1) \)
  2. \( (1, 9) \)

Graphing the Function

To plot the two points:

  • Plot the point \( (0, 1) \) on the coordinate plane.
  • Plot the point \( (1, 9) \).

The graph of the function \( y = 9^x \) will show an exponential growth curve, starting from \( (0, 1) \) and rapidly increasing as \( x \) increases.

If you were to graph a larger portion of this function, you would see that it approaches \( 0 \) as \( x \) goes to \( -\infty \) and rises steeply for positive values of \( x \).
