Answer:
We have the function y = k(x).
We want to define a new function p(x), such that is equal to k(x) but translated down 3 units.
When we have a general case of a function y = f(x), the function g(x) = f(x) + A is a translation of A units up (if A is positive) or A units down (if A is negative).
Then if we want to go 3 units up, we should have:
p(x) = k(x) + 3.
So now our points are:
(x, y) = (x, p(x)) = (x, k(x) + 3)
So for all the points the y-coordinate has ben mooved 3 units up.
