Find the Average Rate of Change of the Function from x1 to x2 (Precalculus)

Learn how to find the average rate of change of a function between two x values. We discuss what the average rate of change represents on a graph and the formula for calculating rate of change. We also discuss how to find the corresponding y values so that you have two ordered pairs with which to work.

Thanks so much Mario you've saved my grade more times than I can count 😂

[agdstudio]

Thanks so much!! You have no idea, I'm taking a summer course for Pre Calculus and our teacher goes by the topics fast because of time, so thank you for making this video so I can learn with my own pace!

[liamjarrott]

I’m a little confused, hoping I’d find something in the comments, It looks like you did y1-y2 over x1-x2.

[sheilagonzalez]

one two minute video solved all my problems for tonight thank you so much!

[brionnapatton]

I’m horrible in math. You did it so fast I got lost when you said 9*2=18. Where did the 9 come from?

[sebastianwyman]

Dude seems like a really nice guy. Was browsing the web as all I needed was a very quick answer - this helped immediately. Thank you Mario!

[Cosmicly]

Thanks! This helped a lot with one of my specific assignments. I have subscribed, and I have a feeling that your channel will help me a lot in the near future!

[ansimp]

what was the reason for going so fast?

[albanygarcia]

[sathviksunkara]

Thank you Mario this video helped me on today's assignment.

[sarapewitt]

Wow!! Thank you so much! You just made this so easy for me. Had no idea what my teacher was doing.

[jerryexe]

Csec maths was good today thanks for the help

[lillygun]

Thank you so much! I was confused, but you made it a lot easier to solve and understand!

[zhezheqian]

Mario can you go over the instantaneous rate of change sometime? Thank you

Note to self, if anyone is planning to take Calculus, you will see it again in Calculus 1. After all, Calculus 1 is basically where your Algebra, Trigonometry and perhaps Geometry (particularly Analytic Geometry) skills could pass you or fail you. So make sure you are strong in all 3 math classes. Otherwise, you are going to struggle with Calculus 1 and beyond (e.g. Calculus 2, Calculus 3, Linear Algebra, Differential Equations, etc.).

something about the part where you plugged the numbers seem off

Mario, I can tell you know what you're doing, however, you have to understand that we don't. Your speed explaining the problem was beyond my comprehension. You're handing me over a steak, but what I need is Gerber Baby Food. Break it down for me, dummy-fy the problem that a 5th grader can understand, slow down ( and I mean, speak slower and explain slowly verbally and on the board ); let me swallow before I can grab another bite of information. Again, I can tell that you know your math quite well, but your delivery was not on par. Anyways, thanks for having content like this available for people like my (over 40yr old) trying to get back on the college wagon and do an engineering degree.... struggling with math miserably... and these videos do help. Once again, thanks.

[alicianowell]

im confused, u said 9X2 is 18? where did u get 9 from ? its a tutorial but not showing the work

[bellion]

Oh wow i didn't know it was that easy

[seanbrady]

This video is so much better then the other bullshit ass video
