The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. which of the following describes the domain of (g. f)(x)

The set of all real values except 7

Step-by-step explanation:

We are given that,

Domain of the function f(x) is 'the set of all real values except 7'.

Domain of the function g(x) is 'the set of all real values except -3'.

It is required to find the domain of .

Now, we know that,

The composition   of functions and will be defined where the function is defined.

Since, the domain of f(x) is 'the set of all real values except 7'.

Thus, the domain of is also 'the set of all real values except 7'.

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
