Question

Concider the functions: f(x)= (2/3)x and g(x)=(2/3)x-3+2. Which statement is true regarding the vertical and horizontal translations from f(x) to g(x) ?
A. The function f(x) was translated left 3 units and up 2 units
B. The function f(x) was translated right 3 units and down 2 units
C. The function f(x) was translated left 3 units and down 2 units
D. The function f(x) was translated right 3 units and up 2 units

Answer 1

The function g(x) is a translation to the right of 3 units and up 2 units of f(x), so the correct option is B.

Which statement is true regarding the vertical and horizontal translations from f(x) to g(x)?

For a given function f(x), we can write a vertical translation of n units as:

g(x) = f(x) + n

• If n < 0, the translation is downwards.
• if n > 0, the translation is upwards.

And a horizontal translation of n units as:

g(x) = f(x + n).

• if n > 0, the translation is to the left.
• if n < 0, the translation is to the right.

Here we have:

f(x) = (2/3)*x

g(x) = (2/3)*(x - 3) + 2

By comparing it with the general translations, we conclude that we have a traslation of 3 units to the right and 2 units up.

So the correct option is B.
