Algebra Expressions, Equations, and Functions Domain and Range of a Function 1 Answer Konstantinos Michailidis Sep 16, 2015 Refer to explanation Explanation: Hence #f(x)=10-x^2=>x^2=10-f(x)=>10-f(x)>=0=>10>=f(x)# So the range is #(-oo,10]# Answer link Related questions How do you determine if (-1, 4), (2, 8), (-1, 5) is a function?
