Domain Restrictions of Rational Functions: And vs. Or

I've seen some of this recently:

I see the convenience of setting the denominator "not equal" to zero.  However, the math represented here is a little flawed.

What we know is the zero product property:
We also know that the inverse of this property holds:
In other words, when the product is not equal to zero, we need both factors to be different from zero.

So, when we teach domains of rational functions like the example above, we're getting a more restrictive domain than necessary.

That's my nitpicky rant for the day.

  17. Making the Transition to Virtual Training & Coaching
    2020 changed everything. For the past 20 years, most of our training and coaching was done face-to-face. Suddenly, everyone has to sell, present and communicate remotely.

    We quickly became experts in the craft of presenting, communicating and selling from afar. Then we set to converting our existing programs to the virtual platform. Next, we built programs from scratch, leveraging remote learning best practices and making them shorter, faster and more engaging. Since then, we have trained and coached hundreds of speakers and salespeople on Zoom, Webex and Teams.
