**Required**

Determine the domain

**This means that we list out possible values of x.**

This implies that x can take any value as long as it is greater than or equal to 0.

<em>**Hence, the domain is all positive real numbers**</em>

**Step-by-step explanation:**

9.94 => 10 (1s.f.)

29.7 => 30 (1s.f.)

Hence we estimate the value of 9.94² * 29.7

as 10² * 30 = 3,000.
