Determine relative min, max, domain, range, and zeros from a graph

👉 Learn how to determine the extrema from a graph. The extrema of a function are the critical points or the turning points of the function. They are the points where the graph changes from increasing to decreasing or vice versa. They are the points where the graph turnes. The points where the graph changes from increasing to decreasing are called the maximum point while the points where the graph changes from decreasing to increasing are called the minimum point.

Brian, I'm dedicating an entire folder in my bookmark favorites to your Pre-Cal playlist.
I wish you were my instructor.
This is fine work, and God is probably a mathematician of some kind.... Keep doing God's work.

I've recently gone back to school after a 15-year break. Your videos are saving me in College Algebra!

[Coreycolay]

He is the best instructor on YouTube!!!

[billlawrence]

Your channel is so good. You explain the math so well. As a lover of mathematics, I enjoy watching you teach! Keep up the great work and have a great day!

Great lecture. Where can I see how get the polynomial from the graph? Thank you

[kausarkhan]

You do a great job teaching. One question should b) x=7 should this be -7? thanks

[ananyakashyap]

can you just upload a video on how to find exact real root and exact no. of distinct real roots for a polynomial by some other method if possible

[teachercheal]

sir im inspited by you. pls keep doing good

[angelhaughton]

I wish you were my teacher for algebra 2! Ugh my teacher now is horrible

[angelsreach]

Dude be my precalc professor lol you kill it

[mathsupportssports]

x= -7 (not x = 7) is a zero


Finding the degree from the number of turning points, consider writing out the equation n - 1 = 4 and solving for n. It seemed the verbal explanation was not helping.

I think this stuff is easy in general. we're here cuz we struggling because our attention span in class is poop which makes everything rocket science.
