Work Step by Step
$f(x)=x^{3}$
(Using desmos.com) we graph f(x) (blue dashed graph).
By hand, plot the points on the graph of $f(x)$:
(-2,-8), (-1,-1), (0,0), (1,1), (2,8)
and join with a smooth curve.
$h(x)=-f(x),$
so the graph of $h$ (solid red line)
is obtained from the graph of f by
reflecting it across the x-axis (solid red line)
Using the above points, $(x,f(x))$
plot the points
$(x$, $-f(x))$
and join with a smooth curve.
