Instructions: Exponential regression formula for the data (x, y) is: y = exp (c) exp (m x), where m is the slope and c is the intercept of the linear regression model fitted to the data (x, ln (y)). Step 1: The function is . You would use a calculator to find that value. If one of the data points is the y- intercept \left (0,a\right) (0,a) 25 = a2 25 = a 2. = 8 Evaluate the power. Both these answers assume the form f(x) = ab^x; however, this presumes that the exponential function has an asymptote at x=0; it also assumes that base is important, but b can always be converted to e. Now you can also solve this problem with the more general f(x) = ae^x + c, which is still exponential, but now leaves the asymptote open to other possibilities and uses the natural base.
