To create an exponential model based on the given dataset, we can first analyze the y-values to find a pattern. Observing the y-values:

  • For \( x = 0 \), \( y = 6 \)
  • For \( x = 1 \), \( y = 12 \)
  • For \( x = 2 \), \( y = 24 \)
  • For \( x = 3 \), \( y = 48 \)

Let's look at the ratios between successive y-values:

  • From \( 6 \) to \( 12 \) is a factor of \( 2 \) (12/6 = 2)
  • From \( 12 \) to \( 24 \) is also a factor of \( 2 \) (24/12 = 2)
  • From \( 24 \) to \( 48 \) is again a factor of \( 2 \) (48/24 = 2)

This consistent doubling suggests an exponential model of the form:

\[ f(x) = a \cdot b^x \]

We know \( f(0) = 6 \). Therefore:

\[ 6 = a \cdot b^0 \Rightarrow a = 6 \]

Now, knowing the ratio motif (b = 2), we can express the model as follows:

\[ f(x) = 6 \cdot 2^x \]

Thus, the appropriate exponential model that fits the data is:

\[ f(x) = 6(2^x) \]

So the correct response is:

f(x) = 6(2^x).
