What is the domain of the function y=^3 square root x - 1

Option A is correct

Step-by-step explanation:

Given the function:

Domain states that the complete possible values of x for which function is defined.

The domain of a cube root function is the set of all real number .

Since, the given function is cube root function.

therefore, the domain of the given function is the set of all real number for which function is defined.

i.e,

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
