WebSep 7, 2024 · The inverse of g(x) = x + 2 x is f(x) = 2 x − 1. We will use Equation 3.7.2 and begin by finding f′ (x). Thus, f′ (g(x)) = − 2 (g(x) − 1)2 = − 2 (x + 2 x − 1)2 = − x2 2. g′ (x) = 1 f′ (g(x)) = − 2 x2. We can verify that this is the correct derivative by applying the quotient rule to g(x) to obtain. g′ (x) = − 2 x2. WebInverse means the opposite. So in math, an inverse operation can be defined as the operation that undoes what was done by the previous operation. The set of two opposite operations is called inverse operations.
