Answer:

-1

Step-by-step explanation:

There are things called domain and range.

Domain is all the x values and range is all the y values.

Since in your picture the parabola only seems to be touching -1, that is your domain.

Answer:

The domain is all real numbers.

Step-by-step explanation:

Imagine the arrows extending forever. There is nothing to the left or right to stop them from growing infinitely far apart, and <u>including all numbers</u> in between! The domain is vast!

It may help to think of range like a mountain range with peaks and valleys. A parabola's vertex might be the peak of a mountain or the low spot in the valley.

In the graph shown here, the vertex is at (-1,0) The range can't go any higher. But the arrows point forever to negative infinity. So if the question asked about the range, it would be all numbers less than or equal to 0.

I hope this helps you understand better!
