Determine the open intervals on which the graph of f(x) = x - 4cos x is concave upward or concave downward
bazaltina [42]

The graph of the function f(x) is

  • concave upward, when f''(x)>0;
  • concave downward, when f''(x)

Find f''(x):

1.

f'(x)=(x-4\cos x)'=1+4\sin x;

2.

f''(x)=4\cos x.

Now:

1. when 4\cos x>0, the graph of the function is concave upward and this is for

x\in \left(-\dfrac{\pi}{2}+2\pi k,\dfrac{\pi}{2}+2\pi k\right), \text{ where } k\in Z.

2.  when 4\cos x the graph of the function is concave downward and this is for

x\in \left(\dfrac{\pi}{2}+2\pi k,\dfrac{3\pi}{2}+2\pi k\right), \text{ where } k\in Z.
