Answer:
The given function of volume v(x)=(18-2x)(3-2x)x is true for certain boundaries of x which is mentioned below.
Step-by-step explanation:
The equation for the volume is represented as:
v(x)=(18-2x)(3-2x)x
18-2x > 0
or, 2x < 18
or, x < 9
or, 2x < 3
or, x < 1.5
This develops the boundary for x as,
0 < x < 1.5
