Question

If the graph shown below represents $f\left(x\right)=\sin x$, then which of the following options describe $p\left(x\right)=\sin 2x$?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

we have the graph of $\sin x$ and graph of $\sin 2x$ is asked.
Clearly, this is a problem of transformation of graph from $f\left(x\right)$ to $f\left(ax\right)$.
In this, we divide the points on $x-$ axis by factor $a$ i.e., $2$, clearly depicted by option (b).
