Let f ( x ) = 10 x + 14 f − 1 ( x ) =

Agata [3.3K]

Answer:

f^-1(x) = (x -14)/10

Step-by-step explanation:

You can find the inverse function by solving for y:

x = f(y)

Here, that is ...

x = 10y +14 . . . . . use the definition of f(y)

x -14 = 10y . . . . . . subtract 14

(x -14)/10 = y . . . . divide by the coefficient of y

So, your inverse function is ...

f^-1(x) = (x -14)/10
