.

If you plot the graphs of the two functions, onto common axes, then the solutions for f(x) = g(x) will be the points at which the two graphs intersect one another.

Refer to the graphs in the image below

( as plotted by Wolfram Alpha ), where it is evident that the blue linear curve intersects the red cubic curve at three points.

So you should select Answer: “… C) three …” .
