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.

3/4=j-1/2 solve the equation check your solution
DIA [1.3K]
3/4= j-1/2
first to add 1/2 to both sides to solve for j 
3/4 + 1/2= j
second you find a common denominator in order to add 3/4 and 1/2, the common denominator would be 4, you would have to change 3/4 at all because the denominator is already 4 but in order to make the denominator of 1/2, 4 you would have to multiply both the denominator and numerator by 2 so 
3/4 + 2/4 = 5/4
so 5/4 =j

to check your answer you plug 5/4 in for j 
3/4 = 5/4 -1/2
again you need to find a common denominator between 5/4 and 1/2 which again would be 4, and again you wouldn't change 5/4 but you would multiply both the numerator and the denominator of 1/2 so 
3/4= 5/4-2/4
5-2= 3 and you would keep the 4 so 
5/4 - 2/4 = 3/4

so j =  5/4
