Answer:
\text{Domain = -}\infty\text{ < x < }\inftyStep-by-step explanation:

The given function is:


f(x)=5x^2+2x-1

Note that the domain of a function is a set of all the input values that will make the function valid

Since all real values of x will make the function f(x) valid, the domain of f(x) is a set of all real numbers.

This can be written mathematically as:


\text{Domain = -}\infty\text{ < x < }\infty
