Answer: The set of all real number.

Step-by-step 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.

<u>Answer:</u>

All real numbers

<u>Step-by-step explanation:</u>

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.

AB is a straight line workout the size of angle X

Hoochie [10]

The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.

Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.

The straight line formed a 180° angle. The resulting equation is as follows:

⇒x+42°+29°=180°

⇒x=109°

Hence, the value of the x will be 109°

The complete question is:
