Question

In the following exercises, determine whether each equation is a function. y-3x^3=2

Answer 1

Given the function:

`y-3x^3=2`

Clearing y:

`y=3x^3+2`

And now, we are going to analyze the domain of the function:

As you can see, the function is a polynomial. In this case the function will exist at all values ​​of x.

that is, there will always be an image in y for each value of x.

Therefore, the equation is a function.
