Ariel entered an elevator and went down 6 floors. then, she went up 8 floors and down 5 floors. how can ariel get back to the floor where she entered the elevator?

Interval for the function has local minimum of 0 is [2, 4].

Step-by-step explanation:

We need to find the local minimum of 0 in the given function's graph.

In mathematics, local minimum is a point on a graph whose value is less than all other points near it.

See that, graph value 0 is lie on the x = 3 and in interval x = 2 to x = 4

So, final answer is :

Interval for the function has local minimum of 0 is [2, 4].

That's the final answer.

I hope is helps you.
