The third one is not a function.
Because 4 appears twice in the range and it’s image is different each time.
The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.

Answer:
V = 432 m³
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = bh ( area of triangular base, with b the base, h the perpendicular height)
Here b = 16 and h = 6 , then
A = × 16 × 6 = 8 × 6 = 48 m²
Then
V = 48 × 9 = 432 m³
