Question

consider the function f(x)= x+3cosx for 0 11 years ago

Answer 1

btw the last equation should be x+3cosx=4 . NOT x+3xcosx=4

Answer 2

thank you, but i need to show calculus, not just type it into the calculator and graph it.

Answer 3

well a couple of things... f(x) = 4 has no roots, its a horizontal line through y = 4

so if you graph the 2 curves you are looking at the point of intersection... as the solution.
