The option A is showing the domain ans the range of the function F(x) as inverse of F(x).
<h3>What is inverse function?
</h3>
In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by 
Here in the graph we can see that the option A has the clear range of the function.
Hence the option A is showing the domain ans the range of the function F(x) as inverse of F(x).

Answer:
1/6
Step-by-step explanation:
Probability = number of ways it could happen / total number of outcomes
Since there are 2 people with brown eyes, so the numerator is 2.
Since there are 12 people in total, the denominator is 12.
Probability = 2/12 = 1/6
Answer:
4x^2 +9xy +6y^2
Step-by-step explanation:
Combine like terms. I find it useful to factor out the variable part of the expression so I can see what coefficients are being combined.
7x^2+5xy-3y^2 - (2x^2+3xy-5y^2 + x^2-7xy-4y^2)
= (7 -2 -1)x^2 +(5 -3+7)xy +(-3 +5 +4)y^2
= 4x^2 +9xy +6y^2
Area of parallelogram: lw = 9(5)=45m
Area of triangle: 1/2bh = 1/2(9)(8) = 36m
So total area = 45+36=81m
1 mi and 900 ft,1 mile = 5280 ft
