Question

Look at this graph of a function. (y is a function of x)

Answer 1

D.means all real numbers greater or equal than -4

Step-by-step explanation

Step 1

The domain of a function is the set of all possible inputs for the function, x-values

Now, in the graph we can see, the line starts in -4

the, the domains goes from:

`-4`

to

the arrow indicates the functions continues to infinite, Hence

`\infty`

then, the domain is

`\lbrack-4,\infty\rbrack`

Step 2

in other words

`\lbrack-4,\infty\rbrack`

means all real numbers greater or equal than -4, so the answer is D
