Evaluate the function for some arbitrary values of x (at least two, but three or more would be better to ensure no errors).
Plot the resulting coordinate pairs and draw a line through them.

Explanation:

Sample points

{:(underline(color(black)(x)),color(white)("XXX"),underline(color(black)(f(x)))), (-2,,9),(0,,-1),(2,,-11) :}
