WebSep 5, 2024 · Rational functions may seem tricky. There is nothing in the function that obviously restricts the range. However, rational functions have asymptotes: lines that the graph will get close to, but never cross or even touch. In the graph above, the domain … WebIn general, we can calculate the domain of a rational function by identifying any point where the function is undefined. This means finding any point that makes the denominator equal to zero. To find the range of a rational function, we can identify any point that cannot be reached with any input. This is generally found by considering the ...
WebIt is very important to remember that the domain restrictions occur before any simplification process! This means that, although the domain restriction for x= 2 x = 2 can be “simplified away” it is still a domain restriction of the original function!
