Question: What is the domain?

Answer 1

Explanation:

From the graph, it can be seen that the parabola convers every x-value from the left until at x = -1 and then it stops and continues to x = -1 again but in a straight line all the way to positive infinity.

But notice that at x = -1 form the parabola, the circle dark meaning that it it is included in the domain thus the square bracket and for the straight line as well at x = -1, the circle is not dark meaning it won't be included in the domain.

hopefully this makes sense

:)

Answer 2

`\boxed{\sf (-\infty,-1]\cup (-1,\infty)}`

Explanation:

• Domain of a function is the input of the function.
• Range of the function is the output of the function after putting the values from domain.
