Best ResponseYou've already chosen the best response.2That explanation works. Show that dy/dx = 0 has no solutions In an informal way you could explain it like this The graph of 1/(x^2) gets closer and closer to the x axis as x gets larger. It never hits the x axis. If you had a horizontal tangent, then that would either imply you have a flat part or a turning point. You can't have a flat part because it keeps getting closer and curving to the x axis. You can't have a turning point because again, it's getting closer and not turning away
