Answer:
f-¹(x) = (4- x)/ 3
Step-by-step explanation:
inverse of a function is nothing but the value of x in terms of f(x)
like
if we write f(x) as y we'd get
y = - 3x + 5
so, ill express x in terms of y:-
y= -3x + 4
y + 3x = -3x + 3x + 4
y - y + 3x = 4 - y
3x = 4 - y
x = (4 - y)/ 3
soo, the inverse of the function is x = (4- y)/ 3
mostly we write the inverse in terms of x, hey! don't get confused, when i say this, I simply mean that we're gonna replace y with x and x with f-¹(x).
therefore,
f-¹(x) = (4- x)/ 3
Answer:
[tex]f^{-1} (x)[/tex] = [tex]\frac{-x}{3} + \frac{5}{3}[/tex]
Step-by-step explanation
y = -3x +5 ---> x = -3y + 5 -> y = [tex]\frac{x - 5}{-3}[/tex]
