Answer:
all real numbers or
Step-by-step explanation:
since both f(x) and g(x) are polynomials, neither of them have restrictions on their domains. Since they can be defined for all real numbers. It's not like the square root which has a domain of (0, infinity), or log x which is defined only from (0, infinity). So adding these two polynomials would result in a domain of all real numbers.
The Solution.
The given points are
The formula is
In this case,
Therefore,
Hence, the correct answer is (-1, 4) (option 3)
