Step-by-step solution-:

The **Domain** of a graph consists of all the input values shown on the x-axis

We can observe that the graph of f(x) extends horizontally from 0 to 7 on the right without bound

, so the domain is:

x\in [0,7]

The **Range** is the set of possible output values, which are shown on the y-axis.

We can observe that the graph of f(x) extends vertically from 0 to 70 so the Range is:

f(x)\in [0,70]

The required answer is:

Domain is:

x\in [0,7]

Range is:

f(x)\in [0,70]
