Here f(x) and g(x) and the two functions across which the following arithmetic operations are performed. (f + g)(x) = f(x) + g(x) (f - g)(x) = f(x) - g(x) (αf)(x) = αf(x) (fg)(x) = f(x).g(x) (f/g)(x)

Functional equations are equations where the unknowns are functions, rather than a traditional variable. However, the methods used to solve functional equations can be quite different than

The notation for this function is H(x), and its equation is written as: {eq}H(x) = \begin{cases} & \text{0 if } x 0 \\ \end{cases} {/eq}

Functions essentially talk about relationships between variables. You get one or more input variables, and we'll give you only one output variable. I'll put value. And you can define a
