  • 4:48 He says "at zero we will still be at zero" should be at x=0 we will still be at y=1 JUST FYI!!! thumbs up to keep this up top!

  • @theninjadang Yeah, in the actual course this is from, there is a dashboard around the video and it corrects his mistake in the video. This happens and he usually catches himself and calls out the mistake. If he doesn't and we use the footage, it's noted in the course so the viewer knows what he said doesn't match what is written. Good catch!

  • how do u graph y=6^x

  • @champhouse3 You need to set values for x and then solve the function. So, x=2 would result in y=36. That is one of your coordinates. Keep plugging the values in and solving for y and you'll get several coordinates that will enable you to graph the function.

  • Thank GOD for teachers like you on youtube. You may have just saved me from having to drop my math class.

  • @IRLWHM I am so glad we saved you from dropping your math class! That would be AWFUL! Many students use our YouTube videos and even our online courses as tutors when they are having difficulties in their classes. I hope we can continue to help and keep you in your classes! :)
