Answer:
[- 4, ∞ )
Step-by-step explanation:
the expression inside the radical must be greater than or equal to zero
x +4 ≥ 0 ⇔ x ≥ - 4
domain: x ∈ [- 4, ∞ )
The picture is how I solved it and it will be correct
Answer: 23
If x=-1 then (-1) to the power of 3 = -1 and (-1) to the power of 2= 1
3(-1)^3= -3
2(-1)^2= 2
-3+2+25= 23
