Exponential function, in mathematics, a relation of the form y = ax, with the independent variable x ranging over the entire real number line as the exponent of a positive number a. Probably the most important of the exponential functions is y = ex, sometimes written y = exp (x), in which e (2.7182818…)

What is the exponential function formula?
An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x. The exponential function is an important mathematical function which is of the form. f(x) = ax.
What is exponential function and example?
Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. ... An example of an exponential function is the growth of bacteria. Some bacteria double every hour. If you start with 1 bacterium and it doubles every hour, you will have 2x bacteria after x hours. This can be written as f(x) = 2x.
How do you write an exponential function?
y=abxWrite the general form of an exponential equation. y=3bxSubstitute the initial value 3 for a. 12=3b2Substitute in 12 for y and 2 for x.
What is exponential function in general mathematics?
An exponential function is a function in which the independent variable is an exponent. Exponential functions have the general form y = f (x) = ax, where a > 0, a≠1, and x is any real number. The reason a > 0 is that if it is negative, the function is undefined for -1 < x < 1.
