14. What’s the domain and range?

Answer 1

See below

Explanation:

13) Domain: x -> {-3,-2,-1,0,1,2}, Range: f(x) -> {5}

14) Notice how x can't be -4 as that will make the denominator 0. Therefore, your domain is (-∞,-4)U(-4,∞) and your range is [0,∞) since 0 is the lowest possible real y-value that satisfies the equation (recall that if y<0, you are unable to find the real square root of a real number)
