Question

Need help ASP. find the inverse function of f(x)=3x-4​

Answer 1

f (x) = 1

substitute 1 for x

f (1) = 3 (1) - 4

= 3 - 4

= -1

Answer 2

`y = ( x + 4)/(3)`

Explanation:

Let f(x) =y

y= 3x-4

[interchanging variables]

x=3y-4

[making y the subject]

3y=x+4

Therefore the inverse of the function is

`y = (x + 4)/(3)`
