Option b is true to match the vector field f with the given plot f(x, y)=x, -y
<h3>What is meant by a function?</h3>
The earliest known attempts at the concept of functions can be traced back to the work of the Persian mathematicians Al-Biruni and Sharaf al-Din al-Tusi. Originally, functions were idealized dependencies of one variable on another. For example, planetary positions are functions of time. Historically, this concept was developed in calculus towards the end of his 17th century, and the functions studied were differentiable (i.e. they had a high degree of regularity) until his 19th century ).
Given,
f(x, y) = x, -y
gt; at x⇒∞, y⇒-∞ downwards
at x⇒∞, y⇒+∞ downwards
Therefore, option b is true to match the vector field f with the given plot
f(x, y)=x, -y

The complete question is as follows:
Match the vector field f with the correct plot. f(x, y) = x, −y
Answer:
x=2, -4
Step-by-step explanation:
The equation is . The x-intercept is the point(s) where the function intersects the x axis, so this value can be found by plugging in 0 for y. doing so results in . Then, solve for x by moving 18 over, dividing by -2, square rooting both sides, and subtracting 1 to find the value of x.
3/12 = x/16 (multiple both sides by 16)
48/12 = x (simply left side)
4 = x
x=-½ y=0
Step-by-step explanation:
y=2x+1
y=6x-1. this means that
2x-1=6x+1
2x-6x=1+1.
-4x=2. divide both sides by -4
x=-½
thus y=2x-1
y=1-1
y=0
