Question

If the graph of y = f(x) is

Find the graph of $|y|=f\left(x\right)$?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

$|y|=f\left(x\right)$

$|y|$ is never negative. So while we draw the graph of $|y|=f\left(x\right)$, we will have to drop the part where f(x) is negative.

f(x) is negative except at x = 0 (from the given graph). So the graph of $|y|=f\left(x\right)$ will be just one point (0, 0).
