An exponential equation is a nonlinear regression equation of the form y= ab^x. Use technology to find and grab the exponential equation for the accompanying data, which shows the number of bacteria present after a certain number of hours. Include the original data in the graph. Note that this model can also be found by solving the equation log y= mx + b for y. Number of hours, x: 1 2 3 4 5 6 7 Number of bacteria, y: 166 278 469 777 1314 1922 4925 The equation of the regression curve is ^ x y = ___ (____)
