Question

5. The mapping below represents all of the points on the graph of functionf.

What is the domain of f?

Answer 1

Option A

Explanation:

The domain of a function is the set of all numbers that has an image in the co domain. It means that those elements are mapped to other elements and give output values.

From the figure we see that all the elements in
`$ x $` are marked to other elements in
`$ f(x) $`. So, the domain would be:

`$ \{-4, -1, 0, 2, 7\} $`

Hence, Option A.
