Find the exponential function f that models this data Round

Find the exponential function f that models this data. Round the coefficients to the nearest hundredth. f(x) = (1.78)(1.63)^x f(x) = (1.32)(5.97)^x f(x) = (1.63)(1.78)^x f(x) = (5.97)(1.32)^x

Solution

mean of x = 7.5
mean of y = 47.05255076
correlation coefficient r = 0.993975118
A = 5.9734556
B = 1.316783383

So, exponential function = AB^x = 5.97*1.32^x (option D)
