We want to know the effect that the number 4 has on the graph of:

compared with the graph of

For doing so, we remember the basic transformations of the functions:
If we have a transformation of the type: f(x-c) the function is f(x) shifted c units:
• to the ,right ,if c is ,negative
,
• to the ,left ,if c is ,positive
In this case we have a factor

of the function, thus, this means that the function is shifted 4 units to the right
