Writing Recursive Equations for Quadratics 

RU-vid is a better teacher than my actual teacher

THANK YOU SO MUCH! This video helped me so much! As an 8th-grade algebra student, I was always confused but now I'm not. Thank you! Greatly appreciated.

Touche! Nicely done. I'm a Alg 2 teacher and great learning!!!

thank you! after all the videos i watched i finally understand. i originally thought to check you plug the x into the equation to match up with your f(x), but i totally get it now

thank you! the way you explain it makes sense

Thanks bro this really helped me with my homework.

Thankyou so much! This helped me so much and you even explained it better than my honors algebra 2 teacher lol 😂

Thank you!

I subbed it in multiple times and it did not work, I am very confused. EDIT: I figured it out this video is a lifesaver So basically when subbing in, it produces the difference (as it should). For example with 14x-7 after subbing in x, it produces the difference not f(x) - this was a careless error so I hope that I prevented others from making this mistake Thank you soooo much for this video!! I am now subscribed 😊

thank you!!

Hi mr ohashi

Why can’t I get this to work with negative numbers?

so if i am doing tis for a linear equation i still do f(n-1) or do i do n-1

THANKS

why is it negative 1?
