# Thread: Transformation: finding new coordinates

1. ## Transformation: finding new coordinates

Consider the transformation f(x) ----> f(2x-1). Suppose a point on f(x) is f(3)=2.

What is the new x-coordinate after the transformation to f(2x-1) ?

2. The new x-coordinate after tranformation is $2\times 3-1 = 5$ , the y-coordinate can only be found once you know the actual function for $f(x)$

3. Thank you very much, that really helps
