Question

What is the inverse of f(x)=3x-1

Answer 1

Answer:

$\frac{(y + 1)}{3}$

Step-by-step explanation:

Call $f(x) = y = 3x - 1$

Now, $y + 1 = 3x$

$\implies \frac{y + 1}{3} = x$

This is the inverse of the given function.

You can cross - verify it by substituting a point, say, $(1,3)$

We see that the point satisfies both the equations.
