This calculator solves equations that are reducible to polynomial form. Math can be confusing, but there are ways to clarify questions and get the answers you need. Entertainment-- I'm looking at data from the coronavirus outbreak. This is called the general form of a polynomial function. To compute the value of y, we will use the EXP function in Excel so that the exponential formula will be: =a* EXP(-2*x) Applying the exponential formula with the relative reference Relative Reference In Excel, relative references are a type of cell reference that changes when the same formula is copied to different cells or worksheets. Our new Instant Professional Tutoring service provides you with access to a tutor 24/7, so you can get help when you need it, no matter what time it is.
