Domain and Range of a Function Given a Formula

Missed the previous lesson?

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

[Batcaveqq]

Why does it feel like I'm always watching math videos but never actually retaining the information?

[Xurik]

from the bottom of my heart, thank you for helping me throughout the years

[Teemabear]

I'm starting to think I have a learning disability.

[hady]

I'm watching this video and I still don't understand. God bless me.

[tessa]

low-key freaking out cause I took a high level in math thinking i'd do well. But all i've learned so far is that I'm as smart as a rock :)

[amdelrushjunebesquillo]

Im just smilling in emotional pain throughout the video.. and im trying yo learn this for online class😃.

Then IS THE DOMAIN OF 3x²+6x-2 ?!!

[nuckchorris]

Dominix and Rangey, That's how my teacher put it to remind us that the domain=x an the Range=y

[lupinqs]

not me crying right now because i have a test in a couple days and i was supposed to learn this forever ago

[akirashalf]

When I have a quiz about this 20 mins from now but I still can't learn it 👁️👄👁️

[Cycy]

Why does my brain can't function when I heard the word math?

[ilovehuhyunjin]

Wow I learned this lesson in just 8 minutes while my prof was teaching for 1 hour I can't even understand a single thing. Thanks man, you're the real MVP!

[patjackiecannon]

im just stupid I think, ive watched so many videos and I still don't understand

[izzyrobot]

Why can't my math teacher teach this well?

[gleczee]

Why does my brain stop functioning when I heard the word function

[yoonbumi]

My mind has made the decision to shut down when it hears anything about numbers adding subtracting multiplying or dividing

[kao]

My math teacher has not given the virtual students(my school is in person with the option to be online) a single lesson but still expects us to understand and do the homework. These videos are my only hope lol.

Khan academy helped me do well on my placement test for college, and is now helping me get through my precalculus algebra and trig classes 💚💚💚
Thank you!!!
