Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction
21.192 can be written as 21 192/1000 so yes its rational
i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.
Hope this helps :P
Answer:
Domain = All real numbers
Range = y ≥ 0
Step-by-step explanation:
As for the domain... you can substitute any value for x and get a mathematical response. Therefore... the domain is all real numbers
Because we are finding the absolute value of the entire function... we know that the final answer cannot be negative. (Don't forget that it <em>can</em> still be 0) Since y can only be positive... we define the Range as y ≥ 0
