Question

Select the correct answer. What is the domain of the function f(x) = 4x − 16? all real numbers all positive real numbers all positive real numbers except 4 all positive real numbers except 16

Answer 1

Hello!

Since the function has no undefined points or domain constants the answer is all real numbers

The answer is all real numbers

Hope this helps!

Answer 2

The domain of the function f(x) is:

All real numbers.

Explanation:

We are given a linear function f(x) in terms of the variable 'x' as:

`f(x)=4x-16`

Now we are asked to find the domain of the function f(x).

We know that the domain of a function is the possible set of the x-values where the function is well defined that is the function does not gives a absurd result.

As we know that the polynomial function i.e. here a linear polynomial function is defined all over the real axis and is also continuous there.

The graph of this linear function will be a straight line.

Hence, the domain of the given function f(x) is:

All real numbers.
