Answer:
The relation between inputs and outputs is given by an equation called the equation of function. Since the outputs are also real values, hence, reasoning by analogy, you may use the arithmetical operation between functions (addition, subtraction, multiplication, division) to produce new functions.
Answer:
C
Step-by-step explanation:
12 + 3x
12 + 3(20)
12 + 60
72
You need x 20 to get to 10000, so do the same with 150 and get 3000, so it is 3000/10000
