Another example of an nth root function is a cube root function, where n = 3: 3√(x). For example, the cube root of -1 is -1: 3√(-1) = -1. Formal Definition of an nth Root Function The formal definition is: n√
afterall), we have a pretty good grasp on the exponential function. Positive integer exponents are just a shorthand for repeated multiplication. Negative integer exponents are just repeated division. Exponents of the form 1/n are just an alternative way of writing the nth root. By combining thes...
Math Pre-Calculus Exponential function What is an exponential function?Question:What is an exponential function?Exponential FunctionAn Exponential Function is defined as an expression given by the form {eq}f(x) = b^x {/eq}, wherein {eq}x {/eq} is a variable and {eq}a {/eq} is a ...
Functions can be as simple as "Jenny offers a smile then Frank blushes," or as complex as the inputs needed to successfully land a rover on the moon. Linear Functions Linear functions are relationships between one variable and the associated outputs. When graphed, the function makes a line,...

Simple definition of exponential smoothing. Includes single, double, and exponential smoothing (Holt-Winters) methods, with formulas.
What Is Exponential Growth? Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function. The formula for exponential growth is V = S x (1+R)T, where S is the starting value, R is the interest rate, T is the num...
By Assumption 1 and the definition of conjugate function, d(λ)d(λ) is ldld-smooth, and d(λ)=−f∗(−HTλ)−hTλd(λ)=−f∗(−HTλ)−hTλ, where f∗f∗ is the convex conjugate of f. However, −d(λ)−d(λ) may not be strongly convex, because only ...
In Definition 2.1, we will often work with the special case \(\mathcal {L}=\lambda \). This is taken to mean the scalar multiplication operator \(u \mapsto \lambda u\) on the vector space \({\mathcal {X}}\). \(\square \)We apply the function to the following problems: ...
