Is (y=x^2) a function

YES!

y=x² is a function.

Step-by-step explanation:

We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.

In other words, we can not have duplicated inputs as there should be only 1 output for each input.

Given the equation

y=x²

Here, for every value of x, there is a unique y-value or output.

For example,

when x = 3, y = 9, when x = 6, y = 36

In other words, it does not matter which x value of chose, there will be only output.

Therefore,

YES!

y=x² is a function.
