Is a function always a relation

Mathematics
1 answer:
ziro4ka [17]3 years ago
3 0

Answer:

No, to be a function a relation must fulfill two requirements: existence and unicity.

Step-by-step explanation:

  • Existence is a condition that establish that every element of te domain set must be related with some element in the range. Example: if the domain of the function is formed by the elements (1,2,3), and the range is formed by the elements (10,11), the condition is not respected if the element "3" for example, is not linked with 10 or 11 (the two elements of the range set).
  • Unicity is a condition that establish that each element of the domain of a relation must be related with <u>only one</u> element of the range. Following the previous example, if the element "1" of the domain can be linked to both the elements of the range (10,11), the relation is not a function.

I would say Song 1 on the top could be NO, and Song 1 on the bottom could be ON, then Song 2 on the very top could be NO again, then on the bottom of the very top could OO, then on the bottom of that could be NN, and on he very bottom could be ON.
Hope this helps.

Write the polynomial of least degree with roots -2, 0, 1.
joja [24]
So since -2, 0, 1 are the roots:

Therefore  x = -2,  x = 0 ,  x = 1

Implies that:

x = 2        x - 2 = 0

x = 0          x = 0

x = 1        x - 1 = 0


Therefore    (x - 2)x(x - 1) = 0

(x - 2)(x - 1) =   x(x - 1) - 2(x - 1) =  x² - x - 2x + 2 = x² - 3x + 2

(x - 2)x(x - 1) = 0

(x - 2)(x - 1)x = 0

(x² - 3x + 2)x = 0

x*x² - x*3x + x*2 = 0

x³ - 3x² + 2x = 0

This is the polynomial with the least degree, because it possible for another polynomial with higher power to still have the same root.

 x³ - 3x² + 2x = 0    is the polynomial.

I hope this helps.
