Question

Qual valor de f (x) = x + 4 xy

Answer 1

f (x) = x + 4 xy

$f(x) = \frac{d}{dx} (x + 4xy)$

$f(x) = \frac{d}{dx} (x + 4yx)$

Use a regra ↓

$\frac{d}{dx} (f + g) = \frac{d}{dx} (f) + \frac{d}{dx} (g)$

$f(x) = \frac{d}{dx} (x) + \frac{d}{dx} (4yx)$

$f(x) = 1 + \frac{d}{dx} (4yx)$

Solução ➡️ f' (x) = 1 + 4y
