Think about the transformations that have to be taken from the function f(x) to get f(5x + 3) and 5f(x) + 3. The first has a dilation of factor 1/5 in the x direction and a translation of 3 units left, while the second has a dilation of factor 5 in the y direction and a translation of 3 units up.

How do these transformations affect the domain and range of the original function?
