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.

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

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 😊
