Observe what happens if the base is1: To evaluate an exponential function with the form [latex]f\left(x\right)={b}^{x}[/latex], we simply substitute xwith the given value, and calculate the resulting power. The constant was named by the Swiss mathematician Leonhard Euler (17071783) who first investigated and discovered many of its properties.
