Question

How do you graph `y=cosx+3`?

Answer 1

Start with the base graph and shift up three units.

Explanation:

Start with just the graph of `f(x) = cos(x)`. This should be memorized.

A number on the end of this function is always a vertical shift. Positive numbers will be a vertical shift up and a negative number would be a vertical shift down. Shifting up three units gives the following graph.
