What is the domain of the following parabola? a u-shaped graph that opens down with a vertex of 2, 3

The domain of this function is all real numbers

Explanation:
The domain of a function is defined as the values of x that we can use to substitute in the function without making the function undefined or violating any of the conditions (if found)

Our given function:
1- has no given conditions to satisfy
2- has no restrictions on the value of x since it cannot be undefined

This means that our domain can be any real number.

Taking a look at the attached graph, we can verify this solution as we can see that as the parabola goes down, the values of x would branch both positively and negatively without any restrictions or discontinuities

Hope this helps :)

Sorry can't answer that question
