Translations are transformations that change the position of the graph of a function. The general shape of the graph of a function is moved up, down, to the right or to the left. The translations are considered rigid transformations. Suppose that k> 0 To graph y = f (x) + k, move the graph of k units up. To graph y = f (x) -k, move the graph of k units down. We have then: f (x) = 2 ^ x g (x) = f (x) + k if k = 2 then, the graph of g (x) is shifted vertically 2 units up Answer: the graph of g (x) is shifted vertically 2 units up
