The actual inverse function is:
![f^{-1}(x) = x^2 + 3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20x%5E2%20%2B%203)
And the domain is [0, ∞).
<h3>
Where is the mistake?</h3>
Remember that for a given function f(x) with a domain D and a range R.
For the inverse function, f⁻¹(x) the domain is R and the range is D.
Here, for the given function the domain is x ≥ 3 and the range is [0, ∞).
Then for the inverse function, which is:
![f^{-1}(x) = x^2 + 3](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%20%3D%20x%5E2%20%2B%203)
(to check this, you must have that):
![f^{-1}(f(x)) = x\\\\f(f^{-1}(x)) = x](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28f%28x%29%29%20%3D%20x%5C%5C%5C%5Cf%28f%5E%7B-1%7D%28x%29%29%20%3D%20x)
The domain will be [0, ∞) and the range x ≥ 3

Answer:
C. y= 14x+20
Step-by-step explanation:
By looking at the table, you can put in the x-values into all of the equations until you find the corresponding y-values that matches with the values in the table. For example: y= 14(2)+ 20, y=48. y= 14(20) +20, y=300. Hope this helped!
Answer:
A
Step-by-step explanation:
Here, we want to get the number that will be in the units place
Six consecutive numbers from 33 are;
33 , 34 , 35 , 36 , 37 , 38 ,
Product of 5 and any of the even numbers will yield 0
That means the number on the unit place is 0
X + y = 180
x = 4y
Plug that in and you get: 4y + y = 180
5y = 180
y = 36
If you want the larger angle, simply plug in y to x = 4y
So: x = 4(36) = 144
The smaller angle is 36 degrees, and the larger angle is 144 degrees.
The answer would be c- 2/6
there are six cups total and three (blake plus two others) friends
there are two ways you can solve this…
1. by making groups
if you look at the picture, you can split it into three groups because that is the number of people, then count how many cups there are in one group which will be your numerator for the denominator six which is the total
2. simple division
divide the total number of cups buy the number of people which is 3
you get two and follow the same process above
