Question

If a function, f(x) is shifted to the left four units, what function represents the transformation?
A. f(x-4)
B. f(x) - 4
C. f(x+4)
D. f(x) + 4

I'm thinking C.

Answer 1

try

Answer 2

I went by thid

y = f(x + n) shifts f(x) n units to the left.
y = f(x – n) shifts f(x) n units to the right.
y = f(x) + n shifts f(x) n units upward.
y = f(x) – n shifts f(x) n units downward.

Answer 3

you are correct, it's the third one.

@AngelCriner :

Hi. Try to remember this [or write it on your notes]:

The vertical shift, k, has a direct effect on the function.
--> If k = x, then the function is shifted up x units.
--> If k = –x, then the function is shifted down -x units.

The horizontal shift, h, has an opposite effect on the function.
--> If h = x, then the function is shifted to the left x units.
--> If h = –x, then the function is shifted to the right -x units.

x = a positive number.
x = a negative number.

Good luck and have a nice day! (´ヮ`)

Answer 6

Oooh thank you! Much needed and hopefully you all have a nice day as well.

Answer 7

You too!

Answer 8

Ohmigosh, I forgot to add something that will help you on questions like these...

This is how a vertical shift looks like..

Answer 9

And how a horizantal shift would look like..
