Answer:

The correct answer is 2 . (1 , 3)

Step-by-step explanation:

A function is used to denote a particular relationship between variables. They can even be visualized as an input-output machine.

Every function has a domain set and a co-domain set. A function maps elements from domain to the elements of co-domain.

Here the domain can be considered as  { 0 , 2 , 5 , 7}.

Here the co- domain can be considered as { 1 , 3, 8 , 2}.

For a function to be a valid function, all elements from the domain should have an image in the co- domain and every element of domain should have exactly one image in the co-domain.

Here the options 1 , 3 and 4 violate the second necessary criteria for the function to be valid.

Hence (1 , 3) is the correct answer.

DerKrebs [107]
Data:

Humans (x) = 2 Legs
Horses (y) = 4 Legs

74 Heads
196 Legs

Solving:

Addition method

\left \{ {{x + y =74} \atop {2x + 4y =196}} \right.

Simplify by (-4) The first equation

\left \{ {{x + y =74(-4)} \atop {2x + 4y =196}} \right.
\left \{ {{-4x - \diagup\!\!\!\!\!4y =-296} \atop {2x + \diagup\!\!\!\!\!4y =196}} \right.
\left \{ {{-4x =-296} \atop {2y =196}} \right.
-2x = -100.simplify(-1)
2x = 100
x = \frac{100}{2}
\boxed{x = 50}

Now, to find the number of horses, I will use the following equation and I will replace the found value, we will have:

x + y = 74
50+y = 74

Number with incognito are to the left of the equality and numbers without incognito are to the right, remembering that when changing of side changes the signal.

y = 74-50
\boxed{y = 24}

Answer:
Humans = 50
Horses = 24
