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

Answer 1

I'm assuming they probably gave you a picture of a graph.
f(x)+4 would move the graph up 4 and f(x) would move it down 4.
f(x+c) and f(x-c) is counter intuitive, as you would assume that it would move towards the negative part of the graph, but it is the opposite. f(x+4) would be shifted 4 units to the left. f(x-4) would be shifted 4 places to the right.

Answer 2

So,
f(x)+b is b units up the y axis
f(x)-b is b units down the y axis
f(x+b) is b units left on the x axis
f(x-b) is b units right on the x axis

Answer 3

No graph but I did include my choices.

Answer 4

Oh, whoops sorry, reading thoroughly is important :P
The answer would be C.
