In writing or word processing programs that allow it, exponents are written as superscript (above the base number). In a plain text editor (like this one), exponents are noted using the *^* symbol.

WebMay 25, 2024 · Find an exponential function that passes through the points ( − 2, 6) and (2, 1). Solution. Because we don’t have the initial value, we substitute both points into an equation of the form f(x) = abx, and then solve the system for a and b. Substituting ( − 2, 6) gives 6 = ab − 2. Substituting (2, 1) gives 1 = ab2.
