College Algebra (6th Edition)

$f(x)=x^{3}$ (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.
