Question

The function f(x) = 2* and g (x) = f(x) + k. If k = 2, what can be concluded about the graph of

g (x)?

Answer 1

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
