A reasonable domain and range is the set of values that exist for the function. The sets that are not reasonable are not considered domain and range. For instance, f(x) = 15√(x - 3)
The reasonable domain is {x | R, x ≥ 3} since you can't have negative value inside the radicand.
The reasonable range is {f(x) | R, f(x) ≥ 0} since the minimum value is 0 [Noting that x = 3 gives f(3) = 15√(3 - 3) = 15√0 = 0]

Answer:
y = - 12x - 42
Step-by-step explanation:
Given
y - 6 = - 12(x + 4) ← distribute parenthesis
y - 6 = - 12x - 48 ( add 6 to both sides )
y = - 12x - 42
