Answer 5

Well, let's find the inverse of f(x) without plugging in any numbers. That way we can see the relationship between a, b, c, and d that we need.
If we start with \(y = \frac{x+a}{b}\), we can find the inverse by exchanging the variables x and y and then resoving for y.

\(y = \frac{x+a}{b}\) becomes \(x = \frac{y+a}{b}\)

Now solving for y, we get:
\[x = \frac{ y+a }{ b }\]
\[bx = y+a\]
\[bx-a = y\]

Now compare our result with g(x). We have \(f^{-1}(x) = bx-a\) and we want it to look like \(g(x) = cx-d\). So these two will be equal to each other if b = c and a =d. Can you see that?
