Use regression to find an exponential equation that best fits the data above. The equation has form
y=abx
where:

a =
Round to two decimal place values.

b =
Round to two decimal place values.

To find the exponential equation that best fits the given data in the form \( y = ab^x \), we'll use logarithmic transformation and linear regression. This involves taking the natural logarithm of \( y \) values and then performing a linear regression on \( x \) and \( \ln(y) \).

### Step-by-step Process:
1. **Transform the exponential model**:
   - Given: \( y = ab^x \)
   - Taking the natural logarithm on both sides: \( \ln(y) = \ln(a) + x \ln(b) \)
   - This equation resembles a linear form: \( \ln(y) = m \cdot x + c \), where:
     - \( m = \ln(b) \) (slope)
     - \( c = \ln(a) \) (y-intercept)

2. **Calculate \(\ln(y)\) for each \( y \) value**:
   - \( x = [1, 2, 3, 4, 5, 6] \)
   - \( y = [1044, 1492, 2408, 3516, 4742, 6853] \)

3. **Perform linear regression** on \( x \) and \(\ln(y)\).

I'll proceed with the calculation to find the values of \( a \) and \( b \).The exponential equation that best fits the given data is:

\[
y = 729.43 \cdot 1.46^x
\]

where:
- \( a = 729.43 \) (rounded to two decimal places)
- \( b = 1.46 \) (rounded to two decimal places)

**Tip:** Exponential models are suitable when the rate of change of a variable increases or decreases proportionally to its current value.
