Given the function f(x)=5x2-10x-4, what is the domain of f

Since it has no denominators containing variables or even-root radicals
containing variables, the domain in that case is always "all real numbers"
or

%22%28%22-infinity%22%2C%22infinity%22%29%22

Your function is a polynomial, that is it is an expression of finite length constructed from variables and constants, using only the operations of addition, subtraction, multiplication, and non-negative, whole-number exponents. Therefore the domain is the set of real numbers. Said another way, there are no real number values that can be substituted for for which is undefined.
