Question
which is the inverse of the function $y = 3(x - 4)$?
a. $y = 3(x + 4)$
b. $y = 3x + 4$
c. $y = \frac{1}{3}(x + 4)$
d. $y = \frac{1}{3}x + 4$
Step1: Intercambiar x e y
Dada la función \( y = 3(x - 4) \), intercambiamos \( x \) e \( y \) para encontrar la inversa: \( x = 3(y - 4) \).
Step2: Resolver para y
Primero, dividimos ambos lados por 3: \( \frac{x}{3}=y - 4 \). Luego, sumamos 4 a ambos lados: \( y=\frac{1}{3}x + 4 \).
