👉 In mathematics, an exponential function is a mathematical function that involves powers of a variable. This means that it can be defined as a power of another variable, where the base (the number above the variable) and the exponent (the number to which the base is raised) are both positive integers or rational numbers. For example, consider the exponential function y = 2^x, where x is any real number. This function defines the value of y as a result of raising 2 to the
