Answer:
they are NOT inverses
Step-by-step explanation:
f(g(x)) = (√(x+3))² -3 = x +3 -3 = x . . . . f is the inverse of g on g's domain
g(f(x)) = √(x²-3 +3) = √(x²) = |x| . . . . . . g is not the inverse of f, except on a restricted domain (x > 0)
Since the relationship is one-sided, we have to say that the functions are NOT the inverses of each other.

Consider the attached graph.
Functions are inverses of each other if one is a reflection of the other in the line y=x (the dashed orange line). Here, only the "beaded" portion of f(x) (red) matches the reflection of g(x) (blue). The "inverses of each other" relationship is not complete.
Answer:
x=3 , x= -2
Step-by-step explanation:
x^2 -x-6 =0
to solve to find the X's we need to factor.
to factor we need to find gcf.
since this problem has no coefficient in front of the x there is no GCF.
So we need to find the multiples of -6
What times What = -6
-3 and 2 = -6
we know x would need to be foiled to create x^2 so x will be in the parenthesis.
(x ) (x )
now we want to put the multiples into parenthesis
(x-3) (x+2)
but we need to set x-3 and x+2 = to 0
the 0 product property.
x-3=0
+3 +3
x=3
x+2=0
-2 -2
x=2
Answer:
what statements?
Step-by-step explanation:
Answer:
45 kilogram = 99.18 pounds AKA D
Step-by-step explanation:
1 kilogram = 2.204 pounds
The weight of an item is 45 kg. We need to convert it into pounds. So,
45 kilogram = 2.204 × 45 pounds
45 kilogram = 99.18 pounds
So, the weight of the item is 99.18 pounds. Hence, this is the required solution.

Answer: 19.2inches³
Step-by-step explanation:
The volume of a cone is calculated as:
= 1/3πr²h
where,
π = 3.14
r = radius = diameter/2 = 3.5/2 = 1.75
h = height = 6
Volume = 1/3πr²h
= 1/3 × 3.14 × 1.75² × 6
= 19.2325
= 19.2inches³
Therefore, the volume of the cone-shaped sandwich is 19.2inches³.
