The exponential model is the most appropriate model for the given data.
<h3>How to determine the appropriate model?</h3>
The table of values is given as:
x 0 1 2 3 4 5
y 4 8 15.9 32 65.2 128
From the above table, we have the following highlights:
- The value of x increases by 1
- The value of y doubles by (approximately) 2
The above highlights is similar to an exponential model, because an exponential model has a constant multiplicative rate
Hence, the appropriate model is the exponential model
