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 )

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
