Question

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) + 20?

The graph of y = f(x) will shift left 20 units.

The graph of y = f(x) will shift down 20 units.

The graph of y = f(x) will shift up 20 units.

The graph of y = f(x) will shift right 20 units.

Answer 1

I think its the third one...

Answer 2

The topic here is "horizontal and vertical translation of graphs."
If you start with y=f(x) and add 20 to that, to get y=f(x)+20, describe the motion of the graph.
