Question

Which is the graph of y = cos(x − π)?​

Answer 1

Answer:

Graph 1.

Step-by-step explanation:

Th graph of $y=\cos{(x-\pi)}$ looks exactly like the graph of $y=\cos{x}$ if we shifted the axes $\pi$ units to the left. This has the visual effect of shifting the graph forward $\pit$$\pi$ units (imagine filming someone and panning the camera to the left; the person moves right in the camera frame).

So the point at $x=0$, which used to be $(0, \cos{0})=(0,1)$ is now $(0,\cos{(0-\pi)})=(0,\cos{(-\pi)})=(0,-1)$, which we can find on the first graph.
