Answer:
(1, 3) can be removed so that the resulting graph represents a function.

Explanation:
A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y.
Here,
X = {-5, -4, -2, 1, 2, 5}
Y = {-4, -3, -2, 1, 2, 3}
Relation from X to Y : {(-5, -3), (-4, -4), (-2, 2), (1, -2), (1, 3), (2, 1), (5, -4)}
This relation is not a function from X to Y because the element 1 in X is related to two different elements, -2 and 3
So, we have to remove either (1, -2) or (1, 3) in order to make this a function.

If x² + xy – 3y = 3, then at the point (2, 1), dy/dx

Scilla [17]

Answer:

Step-by-step explanation:

We have the equation:

$x^2+xy-3y=3$

Take the derivative of both sides with respect to x:

$\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]$

Implicitly differentiate:

$2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0$

Solve for dy/dx:

$\frac{dy}{dx}(x-3)=-2x-y\\$

Divide:

$\frac{dy}{dx}=-\frac{2x+y}{x-3}$

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

$\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5$

Hence, our answer is A.

Rationals are whole numbers no negative numbers or decimals or fractions and Intergers are only negativd numbers. Absolute Value is a negative number changed into a whole number. Hope this helps.
