Answer 1

B) . f(x) and g(x) have the same domain but different ranges.

Explanation:

on edg

Answer 2

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

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 )
