Question

Is this correct I made an educated guess because I don't really understand it

Answer 1

Option (2)

Explanation:

A function 'f' has been given as,

f(x) = 3x + 1

And the inverse of this function is,

`f^(-1)(x)=(x-1)/(3)`

We have to find the value of f(2).

So we will use the expression: f(x) = 3x + 1

By substituting x = 2 in this function,

f(2) = 3×2 + 1

= 6 + 1

= 7

This result tells us the value of the function at x = 2.

Therefore, Option (2) will be the answer.
