what is the domain of f(x)=3x^2-6x+1

Question

determine the domain of the function:f(x)=3x^2-6x+1

Answer 1

The domain of a function is the set of all the numbers that can be put in place of x, for which the function has meaning. Since there aren't any numbers that you can't put into this function (as is true for all polynomial functions), the domain is All Real Numbers.

 

In interval notation, that is  (-∞,∞)
