Answer
Explanation:
Step1: Use a calculator's exponential - regression function
Most scientific calculators or statistical software (like Excel, R, Python's Sci - Py) have an exponential - regression feature. Enter the (x) - values ((3,4,7,8,12)) and the corresponding (y) - values ((149,165,199,210,243)) into the calculator or software.
Step2: Obtain the coefficients
The general form of an exponential regression equation is (y = ab^{x}), where (a) and (b) are coefficients. After running the exponential - regression analysis, we get (a\approx104.97) and (b\approx1.07).
Answer:
(y = 104.97\times1.07^{x})
