To find an exponential model of the dataset presented in the table with the x-values and corresponding y-values, we want to identify the equation in the form of \( f(x) = a \cdot b^x \).
-
Look at the y-values:
- For \( x = 0 \), \( y = 6 \).
- For \( x = 1 \), \( y = 12 \).
- For \( x = 2 \), \( y = 24 \).
- For \( x = 3 \), \( y = 48 \).
-
Identify the base of the exponential model:
- The y-values are increasing, so we will analyze the ratios:
- \( \frac{12}{6} = 2 \) (from \( x = 0 \) to \( x = 1 \))
- \( \frac{24}{12} = 2 \) (from \( x = 1 \) to \( x = 2 \))
- \( \frac{48}{24} = 2 \) (from \( x = 2 \) to \( x = 3 \))
Each time x increases by 1, the y-value doubles. This indicates that the base \( b \) is 2.
- The y-values are increasing, so we will analyze the ratios:
-
Use the initial value:
- Since \( f(0) = 6 \), we can define our function starting point \( a \) as 6.
Putting it all together, we get the function:
\[ f(x) = 6 \cdot 2^x \]
Among your response options, the correct model is:
f(x) = 6(2^x).
