Question

Graph y=5cosx+3?

Answer 1

graph{y=5cosx+3 [0, 15, -5, 8]}
See explanation. It should look something like this.

Explanation:

To graph it on paper, remember that the cosine function follows the pattern Max, Mid, Min, Mid, Max. Since the amplitude is `5` and the midline `y=3`, start at `(0,8)` and use the quarter points to graph the function `(pi/2,3)`, `(pi,-2)`,`(3pi/2,3)` and `(2pi,8)`.
