What is the formula for (f + g)(x)?

Back

(f + g)(x) = f(x) + g(x) - This represents the sum of two functions evaluated at x.

What is the formula for (f - g)(x)?

Back

(f - g)(x) = f(x) - g(x) - This represents the difference of two functions evaluated at x.

What is the formula for (f / g)(x)?

Back

(f / g)(x) = \frac{f(x)}{g(x)} - This represents the quotient of two functions evaluated at x, provided g(x) ≠ 0.
