Explain how the graphs of y=f(x) and y=f(x+4) are related

Both functions are related but one function is shifting to left by four.

SO for example,

f(x)=x^2
the parabola is at the origin (0,0).
f(x+4)=(x+4)^2
The vertex of the parabola is at (-4,0).

In general if a is positive f(x-a) moves f(x) a units to the right. If a is positive f(x+a) moves f(x) a units to the left.
