You only need to know two points to draw a line. So, just calculate any two points by assuming x to be any number.

Given that (9,-8) is on the graph of f(x), find the corresponding point for the function f(x-2)

MrRa [10]

Answer:

(11,-8)

Step-by-step explanation:

f(x-2) determines a horizontal translation 2 units to the right. Since (9,-8) is the point for f(x) then f(x-2) will be the point (11,-8) where 9 has moved two units to the right 11.
