The domain is (-infinity, +infinity)
The range is (5, +infinity)
The length, width, and area will be 25m, 15m, and 375m².
<h3>How to calculate the area?</h3>
From the information given, the scale in the drawing is 2cm : 5m and the length and width are given as 10cm and 6cm respectively.
Length = 10cm = 10 × 2.5 = 25m
Width = 6cm = 6 × 2.5m = 15m
Area = Length × Width
Area = 25 × 15
Area = 375m²
Therefore, the area is 375m².

The first number would be 6 and the second would be 24
x+4x=30, in which x=6
Hope this helped :)
This is because
(that is, replace any instance of <em>x</em> in the definition of <em>g</em> with √<em>x</em> )
and
(replace any <em>x</em> in <em>f</em> with √<em>x</em> - 1)
Also acceptable:
(assuming <em>x</em> is not negative)
