You can download this Exponential Function Excel Template here – Exponential Function Excel Template Exponential in Excel Example #1 In Excel, while working on non-linear trend lines (set of points on an exponential Excel function’s graph) or non-linear graphs, the EXP function in Excel is widely used.Īn exponential function in Excel is also used to calculate the growth and decay of bacteria and microorganisms. Like the LOG function is used when the rate of change in the data increases or decreases, the EXP function in Excel is used when data values rise or fall at increasingly higher rates.

How to Use EXP Function in Excel? (with Examples) The formula calculates the value of the number. The number e is an irrational number whose value is constant and is approximately equal to 2.7182. Exponential Excel FormulaĮxp function in Excel takes only one input, which is required it is the exponent value raised to base e. Things to Remember About Exponential Function (EXP) in ExcelĮxcel has an exponential Excel function called the EXP function, categorized as a Math/Trig function that returns a numeric value equal to e raised to the power of a given number.How to Use EXP Function in Excel? (with Examples).Solve Exponential and Logarithmic Equations (self test). More References and Links Related to Exponential Functions Exponential Functions. The two populations were equal in 2004 + 10 = 2014 Substitute k by ln(3) in the equation A e k = 3 and simplify to obtain
Take ln of both sides to solve for k and obtain If the the half life of this radioactive substance is 20 days.Ī e k e k = 9 and we also know that A e k = 3 hence Where A 0 is the initial amount (at t = 0) and t is the time in days (t ≥ 0). When were the populations of the two cities equal and what were their populations? t is the time in years such that t is positive and t = 0 corresponds to the year 2004. Where P1 and P2 are the populations (in thousands) of cities A and B respectively. Note at t = 0 A = 100 (initial amount) and at t = 10 (half life), A is approximately equal to 50 which half the initial amount 100.įind parameters A and k so that f(1) = 3 and f(2) = 9, where f is an exponential function given by
The amount A of a radioactive substance decays according to the exponential function P1(t') is approximately equal to 128 thousands.įor checking, the graphical solution to the above problem is shown below. Use any of the function P1 or P2 since they are equal at t = t'
Use property of exponential functions a x / a y = a x - y and simplify 110/100 to rewrite the above equation as follows.Divide both side of the above equation by 100 e 0.008 t' and simplify to obtain.Let t = t' be the time when P1 and P2 are equal, this leads to the following equation in t'.When will the populations of the two cities be equal and what will be their populations? Where P1 and P2 are the populations (in thousands) of cities A and B respectively t is the time in years such that t is positive and t = 0 corresponds to the year 2004. The populations of 2 cities grow according to the exponential functions To obtain parameter A, substitute the value of k obtained in the equation 1 = A e k.Take the ln of both sides and simplify to obtain.Use the first equation 1 = A e k obtained in the first step to rewrite 2 = A e k e k as.Use property (1) above to write the term 2 x + 1 as 2 x × 2 in the given expressionįind parameters A and k so that f(1) = 1 and f(2) = 2, where f is an exponential function given by.Questions with Detailed Solutions and Explanations Question 1 Questions on exponential functions are presented along with their their detailed solutions and explanations.
