WebMar 6, 2024 · 1 Answer. Sorted by: 1. You probably need to fit your table to an exponential function that has a negative coefficient for the variable of the exponent, i.e. y = A exp (-bx) You can use the LINEST () function in excel to do that if you linearize the equation: lny = lnA + bx. A scatterplot with a linear trendline will also give you the coefficient. WebMar 13, 2024 · If you have two points, (x 1, y 1) and (x 2, y 2 ), you can define the exponential function that passes through these points by substituting them in the equation y = ab x and solving for a and b. In …

"WebStep 1/2. The exponential function is defined as: y = a ( b) x. As the graph passes through ( − 1, 2), therefore, substitute y = 2 and x = − 1 into the equation: 2 = a ( b) − 1. By using the same procedure, as the graph passes through ( 2, 16), it follows: 16 = a ( b) 2. Solve the system of equations for a and b: Solve for a in 2 = a b − 1.
