Now, consider the given function $g\left( x \right)=-f\left( 2x \right)$.
This function is of the form $g\left( x \right)=-f\left( cx \right)$, where $c=2>1$.
Therefore, in order to draw this graph, first divide each $x\text{-}$ coordinate of $y=f\left( x \right)$ by $c$ and then reflect the new graph about the $x\text{-}$ axis.
