Actions & Examples

Example 1: f(x) = x^2, g(x) = 2*x + 1

Example 2: f(x) = sin(x), g(x) = cos(x)

Formula Used

The sum of two functions $f$ and $g$ is defined pointwise for all $x$ in the intersection of their domains. The fundamental formula for the addition of two functions is given by:

$(f + g)(x) = f(x) + g(x)$

When executing algebraic combinations, like terms are collected and simplified according to standard polynomial or trigonometric reduction rules.
