A representation is the provision of a portrait or a description of an object,
a person, or an observed situation in a particular (defined) way.
- In algebra, functions are used to accurately serve as representation that show equivalence of observed phenomena or system.
- Graphs are used to present data in a pictorial form, such that an end user can more quickly and or easily understand the information conveyed.
- Equations are used to represent equivalent situations in a manner to provide guidance that enable a user of the equation to find the required result or information.
- Tables represent the data in a situation in an organized manner.
- Venn diagrams are used to represent the relationship between group numbers in a set.
Other situations where the term is used are;
- Athletes representing countries in tournaments
The similarity in the usage of the term to algebra is that the athletes have
the attributes of the country they represent, such that the people of the
country are viewed as strong as the athletes representing them.

Answer:
1) f⁻¹(x) = 6 ± 2√(x -1)
3) y = (x +4)² -2
5) y = (x -4)³ -4
Step-by-step explanation:
In general, swap x and y, then solve for y. Quadratics, as in the first problem, do not have an inverse function: the inverse relation is double-valued, unless the domain is restricted. Here, we're just going to consider these to be "solve for ..." problems, without too much concern for domain or range.
__
1) x = f(y)
x = (1/4)(y -6)² +1
4(x -1) = (y-6)² . . . . . . subtract 1, multiply by 4
±2√(x -1) = y -6 . . . . square root
y = 6 ± 2√(x -1) . . . . inverse relation
f⁻¹(x) = 6 ± 2√(x -1) . . . . in functional form
__
3) x = √(y +2) -4
x +4 = √(y +2) . . . . add 4
(x +4)² = y +2 . . . . square both sides
y = (x +4)² -2 . . . . . subtract 2
__
5) x = ∛(y +4) +4
x -4 = ∛(y +4) . . . . . subtract 4
(x -4)³ = y +4 . . . . . cube both sides
y = (x -4)³ -4 . . . . . . subtract 4
