Question

so f '(x) of f(x)=cos(x) would be -sin(x), right? So once that's graphed, what common function would seem to fit the graph?

Answer 1

got no idea what that means

Answer 2

nor I, quite awkward wording.

Answer 3

any options to choose from?

Answer 4

sin(x-pi) maybe?

Answer 5

no options to choose from. sin(x-pi) would essentially be the same graph, but I'm not sure what is meant by common function when referring to the graph.

Answer 6

me either, fill it in and see if it yells at you

Answer 7

wish I could, this one is handwritten alas :[ I'll ask my prof in class. As long as the inverse and the graph are correct, should be fine.
