Compute (f+g)(x), (f−g)(x), (f·g)(x) and (f/g)(x) for two expressions at a given x.
Function operations combine two functions pointwise: (f+g)(x) = f(x)+g(x), (f−g)(x) = f(x)−g(x), (f·g)(x) = f(x)·g(x), and (f/g)(x) = f(x)/g(x) (when g(x)≠0). This calculator evaluates all four operations at a given x value.
Sum
(f+g)(x) = f(x) + g(x)
Quotient
(f/g)(x) = f(x) / g(x), g(x) ≠ 0
The quotient (f/g)(x) is undefined when g(x) = 0. In that case, the quotient field will be empty.
No — function operations combine outputs pointwise (+, −, ×, ÷). Composition feeds one function's output as the other's input: f(g(x)).
