Question 8

f(g(x))=x it is said to be an inverse. you put x as an input into g() and the output from g(x) into f(x) which undid whatever g(x) did. Ok, i wrote that last year, and reading it now makes me realize how hard that is to parse. Maybe a drawing will make it better.
or maybe a pop culture reference.
an inverse of a function undoes what that function does. So if a sneech goes through a machine that puts a star on its belly, and then goes into a machine that takes the star off its belly, the second machine is the inverse of the first.
so. if f(x)=3x-2, and g(f(x))=x, can you find g(x)?

We discussed in class that you have to find numbers that must be excluded from the domain before you simplify a function. So the following function has a domain where x can't equal 1, even though (x-1) on top cancels with the one on bottom. what is this kind of scenario called

Question 14

The video said if the degree of the numerator was greater than the degree of the denominator there is no horizontal asymptote. Which is true. Go to desmos and plug in the following two equations. The linear equation is not a horizontal line, but it does look like an asymptote, why do you think that is?
