Is a function always a relation
ziro4ka [17]

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.

How do I solve f+4/g=6 for f showing my work
V125BC [204]

We have two solutions for this problem based on the given equation.


<u><em>Answer #1:</em></u>

<u>If the given equation was:</u>

f + \frac{4}{g} = 6


To solve for f, we would need to isolate the "f" on one side of the equation.

In case of the above equation, we can simply do that by subtracting \frac{4}{g} from both sides of the equation

<u>This would give:</u>

f + \frac{4}{g} - \frac{4}{g} = 6 - \frac{4}{g}

f = 6 - \frac{4}{g}


<u><em>Answer #2:</em></u>

<u>If the given equation was:</u>

\frac{f+4}{g} = 6


To solve for f, we would still need to isolate the "f" on one side of the equation.

<u>This can be done as follows:</u>

\frac{f+4}{g} = 6 ................> multiply both sides by (g)

f + 4 = 6g ................> subtract 4 from both sides of the equation

f + 4 - 4 = 6g - 4

f = 6g - 4


Hope this helps :)
