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. WebMar 26, 2016 · To do this, you need to show that both f ( g ( x )) and g ( f ( x )) = x. When you’re asked to find an inverse of a function, you should verify on your own that the …
