The function f(x) is shown below:

f(x) = (3)^x - 2

The function f(x) is shifted to the left by 13 units. Which of the following best represents the new function?

f(x) = (3)x + 11

f(x) = (3)x + 13

f(x) = (3)x -15

f(x) = (3)x - 13

oh okay, well when I did it, I got f(x) = (3)x + 11 ?

anonymous · Answer

yeah, but wouldn't it change to 11 since the 2 is already in the equation?

anonymous · Answer

wait you wrote it weird  use perenthesis

anonymous · Answer

well all of the answers are cubed

(3)^x - 2
in my mind and to a computers mind it is read as
