going full circle with one last math notes post to end august! (well, it’s already september first where i live, but shhhh) got a bunch of pending stuff after linggo ng wika but we’re gonna power through 🌱✨ p.s. i really have to master editing my posts hfhfhf if anyone’s got any tips they’d like to share please feel free to reach out :(

Earlier today my math teacher was telling us to graph functions on the board and he ammended a statement/said a un-fun function and my immediate gut reaction was to softly say “that’s what I thought you’d say you dumb fucking horse”

Rational Functions

-- rational functions are quotients of polynomial functions

-- radical functions can be expressed as f(x) = p(x) / q(x), where p and q are polynomial functions and q(x) does not equal 0

-- the domain of a rational function is the set of all real numbers except the x-values that make the denominator zero

Example

f(x) = x^2 + 7x + 9 / x (x-2) (x+5)

p(x) is x^2 + 7x + 9

q(x) is x (x-2) (x+5)

-- the domain of the above example would be all real numbers excluding 0, 2, and -5
