To determine the best model for the given data points:
- When \( x = 1, y = 10^1 = 10 \)
- When \( x = 2, y = 10^2 = 100 \)
- When \( x = 3, y = 10^3 = 1000 \)
- When \( x = 4, y = 10^4 = 10000 \)
From this pattern, we see that as \( x \) increases, \( y \) is proportional to \( 10 \) raised to the power of \( x \). This indicates an exponential relationship.
Therefore, the type of function that best models the data in the table is exponential.
