1. 2. 1 and 3 are decreasing
3. 4.
Answer with Step-by-step explanation:
Since we have given that
a. f: ℝ → ℝ given by f(x) = x + 2
Domain would be all real numbers i.e. (-∞, ∞)
Range would be all real numbers i.e. (-∞, ∞)
b. g: ℝ → ℝ given by g(x) = √x − 1
Domain would be all positive numbers i.e. [0,∞)
Range would be [-1,∞)
c. f(g(x))

Domain would be [0,∞)
Range would be [3,∞)
d. g(f(x))

Domain would be [-2,∞)
Range would be (0,∞)
144 is the answer to 12x12
Answer:
85%
Step-by-step explanation:
We have 30, 35, and 20.
Your question is asking what the total percent is. Since these percents are all on only a single item, we can just add them together.
30 + 30 = 60
60 + 25 = 85
There we go! 85%

Your Welcome, and thanks in advance.
Answer:
Step-by-step explanation:
8(3x - 6) = 6(4x + 8)
24x - 48 = 24x + 48
24x - 24x = 48 + 48
0 ≠ 96
this will have NO SOLUTIONS....because no matter what value u put in for x, they will never be equal.
