Answer:
Domain- [-4,∞) ; Range- [-2,∞)
Step-by-step explanation:
For Domain, we need to find the range of value for x,
As the value for x+4 should be positive or 0 because it is under the square root bracket sign.
x ∈ [-4,∞)
For the range of values, we need to find all the possible value of y
As the value given by the square root will always be greater than equal to 0.
Therefore ,
y ∈ [-2,∞)
225 (since the fraction is over 180° (because 5Π/4 > Π we know that the answer must be bigger than 180° (because 180° = Π (radians)
and its less than 270° because 270° = 3Π/2 or 6π/4
