College Algebra - Lecture 27 - Rational Functions

why do you shift to the right instead of the left when its (-2)? at 14:30 / nevermind ok so you actually say you 'started' at 2 and then subtract 2 and subtract 1 to get to 0,0.

how are you so good at sketching those graphs! Ugh!

[AcaciaC58]

What's so special about an asymptote if the function can go through it?

[Mu5clehead]

wow, you're better than all the math teachers ive ever had

[MrAlexjbabin]

Hey I go to a community school and my teacher is horrible. You're videos are the reason I'm passing with a high A. I'm impressed with how neat you lesson plan and note-giving is. Thanks the most.

[qtchick7242]

Thank you! This really helped me with my homework.

[ketchupguy25]

You have helped me so much. Does Anyone know what the instructors name is?

If i pass my MAT 1105 exam tomorrow...I will champion this uploader

very nice video! thanks a lot!

[aaaaayyo]

Thank you very much

How can you tell what degree your expression (say, P(x)) is if your variable is either part of a logarithmic function or an exponential function. For example, take the function a^x / ln(x). What degree is the numerator and what degree is the denominator?

[blitzmitz]

Wow great explanations! Very clear and straight forward! This will definitely help since my teacher is not exactly "teaching".... It's good to know that I can learn elsewhere to prep for my exam:S

how would you know what values of x and y intercepts to further convince that your graph is right?

[umkc]

I'm not sure what you are really asking, but, assuming you have been given a function of the form y = f(x), any x-intercept is gotten, by definition, by letting y = 0 [because y = 0 precisely when the point of the graph lies on the x-axis and hence has the form (x,0) ] and then solving for values of x that make this happen. Likewise, any y-intercept is gotten by letting x = 0, and then solving for values of y that make this happen. This is a general technique for any function.

@umkc At 0:41:34 how did you know that the function was going to look like that specifically?

[doughauf]

@umkc How do you know that this example at 52:36 is symmetric around the Y - Axis.
