Question

What is the domain of the function on the graph?

Answer 1

That would be all numbers  equal or greater than -3.

Thats the last choice.

Note the solid dot means that -3 is included in the domain

Answer 2

Answer:

The correct option is 4. The domain of the function are all real numbers greater than or equal to –3.

Step-by-step explanation:

Domain is the set of all possible inputs or x-values, for which the given function is defined.

The given graph is defined form -3 to positive infinity. The point -3 included in the set of input because there is a closed circle at x=-3.

So, domain of the function are all real numbers greater than or equal to –3.

$Domain=\{x|-3\leq x,x\in R\}$

$Domain=[-3,\infty)$

Therefore the correct option is 4.
