Rational functions: how to find... Flashcards
horizontal asymptote
degree rules
vertical asymptote
put demonimator equal to 0
what wasn’t cancled for the hole
hole
factor numerator and denominator, and cancel
x-inter
set numerator equal to 0
after hole
y-inter
replace all x’s with 0’s and solve
just put into calculator
end behavior
- as x goes to infinity, f(x) goes to hori asyn
- as x goes to negative infinity, f(x) goes to hori asyn
domain
all x values expect asymptotes
range
all y values expect hole and horizontal asymptote
standard form of a circle
(x-h)^2 + (y-k)^2 = r^2
general form of a circle
x^2 + y^2 + bx + cy + d = 0
the question: f(x) = -15x-4, f(7) is not…
IS NOT THE DIFFRENCE QUOTIENT!!! JUST THE NUMBER
diffrence quoitent questions will have “diffrence quoitent” or formula
the slope for a perpendicular line is the ____ of the orignal slope
oppoiste reciplocal
horizontal aysm
if the degrees are the same…
y=1
horizontal aysm
If the degree of the demoniator is bigger
y=0
horizontal aysm
If the degree of the numerator is bigger
there is no hori aysm
