For a collection of values of #x_i# solve for #y_i)#; plot the pairs #(x_i,y_i)# and connect. Note neither #x# nor #y# can equal #0#

Explanation:

Sample plot values:
#color(white)("XXX"){:(x," ",y), (-8,,+2), (-4,,+4), (-2,,+8), (-1,,+16), (+1,,-16), (+2,,-8), (+4,,-4), (+8,,-2) :}#

graph{-16/x [-22.8, 22.83, -11.4, 11.4]}
