Domain is all the values of x in the closed interval i:e D is [-4;4] because the function is defined for all the values within that closed interval. Range is all the values between and including -9 and 7 i:e R [-9;7]

I need to type a paper on this and I am not sure about if it means using arrows with the different brackets was what it means when it says this? using inequalities and interval notation?

ohw if you use that notation, then your domain will be \[-4 \le x \le 4\] and your range will be \[-9 \le y \le 7\]. Was that helpful?
