Answer:
It seems like you've provided a sequence of characters: "2x, y2". If you are referring to a mathematical expression or a number, it might be a bit ambiguous. If "2x" and "y2" are meant to represent separate entities, then yes, it's possible to have those two expressions together. However, if you meant to form a single number or expression using "2x" and "y2," further clarification is needed to interpret or combine them mathematically.

Answer:
The function is defined as the relation between values of x
and y
for which at each value of one variable (independent), say x
, corresponds one and only one value of the second variable y
(dependent).
A simple allowed algebraic change gives
y=−2x−2.
Now, start giving the value x=0
and finding y=−2
(only one value), then x=1
and y=−4
, and so on. Yours is a true function in which each x
is associated to its y
value.
It is not a function the following relation, always between x
and y
x2+y2=1
because, when x=0
, the above relation gives y2=1
whose solution is y=±1
, because both y=−1
and y=+1
gives y2=1
corresponding to x=0
.
This is the very first concept in the analytic geometry and analysis calculus.
