The domain of the function f(x) = 4 · x² + 12 · x - 5 is the set of all real numbers.
How to determine the domain of a polynomic function
Functions are characterized by three features:
- Domain - The input of all values of x such that the function f(x) exists.
- Range - The output of all values of y associated with the function f(x).
- Relations - Relations between the input and output sets.
In this problem we need to find the set of all x - values of the polynomic function described in the statement. According to function theory, polynomials are continuous and their domain are always the set of all real numbers.
The domain of the polynomic function is the set of all real numbers.
