2. how would u describe the tanformations of the graph y=3x^3 + 5x + x +1? (like dilations, transations, reflections)

Mr F says: Transformations compared to what graph?? Again, the question makes no sense.

2. has 4/x been dilated by the y-axis (not the x-axis, i know how to do it from the x axis) by a factor of 4 or 1/4?

Mr F says: Dilation from the y-axis: f(x) --> f(ax) and the dilation factor is 1/a.

f(x) = 1/x --> f(x/4) = 4/x. a = 1/4 and so the dilation factor is 4.
