Use regression to find an exponential equation that best fits the data above. The equation has form y=ab^x where
a=____
b=_____

Answer 1

Plot the points on the graphing calculator. Then generate an exponential regression equation.

`y = 698.379( {1.131}^(x) )`

So a = 698.379 and b = 1.131 (to three decimal places).
