Key Concepts

Y-intercept

The y-intercept of a function is the point where the graph crosses the y-axis, which occurs when x = 0. In exponential functions, evaluating the function at x = 0 yields the value of the constant multiplier, as any base raised to the power of 0 is 1. This intercept provides a starting point for graphing the function.

Horizontal Asymptote

A horizontal asymptote is a horizontal line that the graph of a function approaches as x tends towards positive or negative infinity. For exponential functions, the horizontal asymptote is particularly important as it represents a value that the function never actually reaches, typically y = 0 when there are no vertical translations.

Range

The range of a function is the set of all possible output values (y-values). For exponential functions, the range is usually restricted to positive values (or negative values if reflected across the x-axis) due to the nature of exponential growth or decay, which never actually reaches zero but gets arbitrarily close to it.

Domain

The domain of a function consists of all the input values (x-values) for which the function is defined. In the context of exponential functions, the domain typically includes all real numbers because there are no restrictions on the exponent when the base is a positive constant.

Exponential Functions

Exponential functions are mathematical expressions in which a constant base is raised to a variable exponent. These functions, typically written in the form f(x) = a · b^x, exhibit unique growth or decay characteristics depending on whether the base b is greater than 1 (growth) or between 0 and 1 (decay). They are widely used in fields such as finance, biology, and physics to model processes with exponential change.

Function Transformations

Function transformations involve altering a base function's graph through operations such as translation (shifting), stretching or compressing (scaling), and reflecting. For exponential functions, vertical stretches or compressions (multiplying by a constant) adjust the steepness of the curve and the y-intercept, while horizontal stretches or reflections can modify the rate at which the function grows or decays.
