Answer:
Hence, option 1 is correct.
Hence, last option is correct.
Step-by-step explanation:
We have given two function
and
Domain is the values x can take and
And range is the values y can take
Hence, x can take any real value in both the functions in f(x) and g(x)
Hence, option 1 is correct
Now, for range
range of f(x) can be any real number
But range of g(x) can be positive number
Hence, last option is correct.
Rest all options are incorrect.
