Which statement best describes the domain and range of f(x) = –(7)x and g(x) = 7x?

The domain and the range of the functions are any real number i.e set R.

Step-by-step explanation:

We are given two functions f(x) = - 7x and g(x) = 7x

Now, it is clear from the above functions that the functions are valid for any real value of x and the corresponding values of y are also real.

Therefore, the domain and the range of the functions are any real number i.e set R. ( Answer )

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

(hint): the answer is in the question.
