Question

What is the domain of the function f(x)=4x-16?

Answer 1

All real numbers

Explanation:

We are given the following function and we are to determine its domain.

For a function, the domain is the set of all input values for which the function is defined to be true.

Here, we cannot have zero as the denominator and neither can we take the square root of a negative number. Therefore, the domain for this function will be all real numbers.

Answer 2

Answer: The set of all real number.

Explanation:

Domain of a function is a set of all possible value of independent variables.

Since, a polynomial is always defined for every real number,

⇒ The domain of a polynomial is always the set of all real number,

Here the given function is,

f(x) = 4x -16,

⇒ Which is a polynomial.

Hence, its domain is also the set of all real number.
