Question

The function fx) = 3x - 20 underwent a translation resulting in the function g(x) = 3x - 26. Which rule describes the translation?

Answer 1

This would be a horizontal shift 2 units to the right. When we right functions, we write (x-h) if it is a horizontal transition to the right, and (x+h) if it is a horizontal transition to the left. 

Since it is a horizontal transition 2 units to the right, the answer would be 

A. f(x-2)

I hope this has helped! :)
