1. Empezamos con la ecuación de la función lineal: y + 4x - 5 = 0

2. Despejamos y : y = -4x + 5

3. Intercambiamos x y y para encontrar la función inversa: x = -4y + 5

4. Despejamos y en términos de x :

x - 5 = -4y

y=\frac{x-5}{-4}

y=\frac{-x+5}{4}

Por lo tanto, la función inversa es f^{-1}(x)=\frac{-x+5}{4}
