I don’t know why I am gettin this question wrong that appears to be the only rational function to me and it says I’m wrong, can you help?
where p and q are polynomial functions. The domain of a ration
Question. Which of the following are rational functions?
f(x) = 0
f(x)
f(x) = e
f(x) =
S
3x+1
T²-4x+5
to search
sin(x)
cos(x)
f(x) = -4x3 + 5x¹ +7 - 18x²
f(x) = x¹/2 - x + 8

All polynomials can be thought of as rational functions.
f(x) =
x³ x
What can the graphs look like?
There is a somewhat wide variation in the graphs of rational function
Example. Here we see the the graphs of four rational functions.
