The inverse of a function is given as √x - 1
<h3>Inverse of a function</h3>
To get the inverse of any function f(x) we need to ensure that it passes the horizontal line test.
Given the following function
f(x) = (x+1)^2
Let y= f(x) to have:
y = (x+1)^2
Replace y with x to have:
x = (y+1)^2
Make y the subject of the formula
√x =y + 1
Subtract 1 from both sides
√x - 1 = y
Swap
y = √x - 1
Hence the inverse of a function is given as √x - 1

Answer:
Marian can order 1,771 combinations
Step-by-step explanation:
In this question, we are interested in calculating the number of combinations Marian can order given that there are 23 flavors that can be served in three ways.
Mathematically, the number of combinations that can be ordered is simply 23C3
This is equal to 23!/(23-3)!3! = 23!/20!3! = 1,771
The number of combinations she can order is thus 1,771 combinations
Step-by-step explanation:
y=-1/2.x+2 =-2 then x=8
the area is S = 
S=121/4
