Given two sets X and Y, a relation between X and Y freely associates elements of X with elements of Y, with no restrictions.
A function is a relation with some restrictions: there must be exactly one element of Y connected with each element of X.
The set X is called the domain of the function, and it represents all the possible inputs that we can feed the function with. As we just said, every element of the domain must have a correlated element in Y.
The set Y is called the range of the function, and it represents all the possible outputs that the function can return.

Answer:
3
Step-by-step explanation:
The value of x = 3/5
y = 1/3
z = 2 4/5
The value of z is in whole number fraction so, let us convert it to improper fraction.
z = 2 4/5 = 14/5
Now let us work out the value of z + x times y. This can be translated mathematically as follows
z + x × y
let us insert the values
14/5 + 3/5 × 1/3
using the PEMDAS principle, multiplication comes before addition therefore, we will do the multiplication before addition.
3/5 × 1/3 = 1/5
14/5 + 1/5 = (14 + 1)/5 = 15/5 = 3
An=a1+d(n-1)
a1=first term
an=nth term
d=common differnce or how much it increases by each time
n=which one
so
originally 3 trees
a1=3
and after 19 years, 84 trees, so a19=84
a19=84=3+d(19-1)
84=3+d(18)
minus 3 both sides
81=18d
divide both sides by 18
4.5=d
an=3+4.5(n-1) or
an=4.5n-1.5
or
t(n)=3+4.5(n-1) or
t(n)=4.5n-1.5
