Question

(consider the function represented by the graph)

What is the domain of this function?

x > ???

Answer 1

Domain of the function in the graph is:

x ≥0

Explanation:

The domain of a function is all those values of x on which f(x) can be defined.

We have to find the domain of the function represented by the graph.

As we can see the graph the function is defined for all the values of x≥0

Hence, Domain of the function in the graph is:

x

Answer 2

we know that

The function is a linear equation

The domain is the interval-------->[0,∞)

All real numbers greater than or equal to
`0`

`x\geq 0`

The range is the interval--------> (-∞,9]

`y\leq 9`

All real numbers less than or equal to
`9`

therefore

the answer is

the domain of the function is
`x\geq 0`
