Practice problem
What is the domain and range of the inverse for the following function? f(x)=x−1x−20f(x)=\frac{x-1}{x-20}f(x)=x−20x−1
Domain: (−∞,1)∪(1,∞)(-\infty,1)\cup(1,\infty)(−∞,1)∪(1,∞)
Range:(−∞,1)∪(1,∞)(-\infty,1)\cup(1,\infty)(−∞,1)∪(1,∞)
Domain:(−∞,20)∪(20,∞)(-\infty,20)\cup(20,\infty)(−∞,20)∪(20,∞)
Range: (−∞,20)∪(20,∞)(-\infty,20)\cup(20,\infty)(−∞,20)∪(20,∞)
Type a concept, like “slope” or “photosynthesis”.
