Question

Given that (3,6) is on the graph of f(x), find the
corresponding point for the function
f(x) – 2.

Answer 1

If we have the function

y = f(x)

and

y' = f(x) - 2

We can say that y' is translated 2 units downward y, so for the same point in  x coord, the y coord will be 2 less

If in y = f(x) we have the point (3, 6) in y' = f(x) - 2 we have the point (3, 4)
