Answer:
-2 will be the answer I think it will help so much my answer
Both are D
First one:
f(g(x)) =f(x^2+3) then you x^2+3 is the x you are going to introduce in the function f
f(x^2+3)= sqrroot(x^2+3-3)= sqrroot (x^2) =x
Second:
you need to leave x alone
y = 3x^2 +1
y-1 = 3x^2
(y-1)/3 = x^2
sqrroot ((y-1)/3) = x
sqrroot ((x-1)/3) = h^-1(x)
Length (L): 2w + 5
width (w): w
Perimeter (P) = 2L + 2w
136 = 2(2w + 5) + 2(w)
136 = 4w + 10 + 2w
136 = 6w + 10
126 = 6w
21 = w
Length (L): 2w + 5 = 2(21) + 5 = 42 + 5 = 47
Answer: width = 21 meters, length = 47 meters
To the tens it is 180 to the hundreds its 200
Answer: The answer is -1 to 2 with open points
This is for both functions check picture below
