Write the equation that results in the desired transformation

Question

The cubing function, vertically shrunk by a factor of $0.2$, and reflected the $x$-axis then $y=$?

Answer 1

HINT: Notice

when a given function say $y=f(x)$ is vertically shrunk (scaled down/scaled up) by a factor $k$ its transformed equation is given as $$y_1=kf(x)$$

Now, the function $y_1=kf(x)$ is reflected about the x-axis, the transformed equation is given as $$y_2=-kf(x)$$
