Thank you for making this app! I am 13 and I really enjoy learning math, science, etc. Khan Academy has really made the process of learning fun, and super interesting. I'm still in shock that such an amazing education platform is completely free!! I am very excited to learn more in the future...once again, thank you so much for Khan Academy.

I like how he pointed out y = f(x) = x+1, which I've found helps students mentally think of what the new notation means by relating it to something they already know.

This is also very useful for beginner programmers, when you say "y = sin(x)", you're actually calling a function sin() with parameter x and overwriting variable y with the result of this function.

I personally think most programming teachers are better at teaching coding concepts than math concepts, I think it's because programming shows your hard work by running your program whereas math usually does not.

This comment had potential for greatness

Hello, everyone. This is a good lecture. This is a good lecture. Everyone, you were born into a good world. And we should thank the people involved in the Cannes Academy. Because their efforts are great. And we have to be careful not to get a corona just like the efforts we make.

I'm self studying math and just got James Stewart's Calculus today. This video makes functions easier to understand.

I could never understand my math teacher at all when he taught this to our class. Now I finally understand THANK YOU

I love watching him explain. I probably would of done far better if I had this growing up.

hi sir thanks for your video. i have some queries with regards to the book i have read online because i cant understand how they get the values in the example. (see below) Ex: Let g(x) be the slope of the line tangent to the graph of y=f(x) at the point (x,f(x)). a. Estimate the values g(1), g(2), g(3) tangent point: (1,0), (2,2), (3,1), (5,-1) Solution: y=f(x) with several tangent lines to the graph of f, we can estimate that g(1) (the slope slope of the line tangent to the graph of f at (1,0)) is approx. equal to 1. Similarly, g(2) approx equal to 0 and g(3) approx equal to -1

I love this. Helped me on my algebra hw.

i would just like to thak you so much , i wouldnt have scored good on my applied maths paper if it wasnt for you. i am so grateful. god bless you

I think I get this so a function is defined as like a machine where any number placed as an input value will get a substitute output valvue . For e.g If I have an operation along with the function F(x)= x + 2 where if I put x as being 1 then when included into the function I get the result of 1 + 2 = 3 .

"... the next larger number that starts with the same letter as a" me: *bruh*

It was simple but in my lecture it was entangled. Now i'm fully saticfied with your explanation. Thank you sir! 🤗

First time watching a Khan Academy video (for personal understanding, not because of the kids). I'm sure it wasn't intentional, but I enjoyed when he solved f(2) = 3 incorrectly. It gave me an opportunity to prove to myself I understood by personally correcting his mistake before he did. Great confidence builder; very empowering! lol

Is this a function F(X)=X^4? Can you explain me how it is a function

@ernestovalverde2394

5 жыл бұрын

I think so. if x == x: return x ^ 4 This is a function in Python which is practically the same as math judging by this video. It's saying if x, raise x to the 4th. F(X) = X⁴. F(3) = 81. Yeah it's a function. I might be wrong though. This is the first video explaining functions (in mathematics) I've watched...this isn't my account btw. I'm a boy...

@joannaathineosmathematics5706

It is for sure and to be specific it's a polynomial function. 4 is the exponent and remains the same. Slope is 1.

@joannaathineosmathematics5706

4 жыл бұрын

Another good explanation to determine if this is a function or not is to see the relation between the two variables x and f(x) . F(x) is always x^4. For every single and different value of x you get a unique and different value for f(x). It's also an even function because of the exponent 4.

I’m taking Math 2H as a freshman this year because I already had math 1H in middle school. School started yesterday and my math teacher just rushed in on math activities already. I was so lost right when he elaborated more on “f being the location and x being the height in a graph” or something along the lines like that. To be fair, I couldn’t hear the teacher all that well Bc I’m hard of hearing and the screen was so difficult to see so I didn’t know what the equations said, what the answers were. There were moments in the class that I thought I figured it out but I actually misread it. Lol. I’m so miserable taking that class. But the teacher is so funny and is good at teaching but is very fast. But I’m stuck here not knowing how to do my homework.
