It helps in calculating the price of groceries such as fruits.
Step-by-step explanation:
Remember, functions are mathematical expressions that represent or shows the relationship between one or more variables.
For example, let's say a young girl wants to shop for 20 oranges in a mall. If we express the price using the function where;
y represents the total cost of the oranges,
20 represents the number of oranges,
x represents the cost per orange (assumed to $0.99)
Then, by means of the knowledge of function, the girl determines the total cost she to be $19.8 (20*0.99).
7. 5/1 x 1/2 = 5/2

12. obtuse
([x]12+ [y]12) = f([x+y}12) = [x+y]4 = [x}4+ [y]4 = f([x]12)+ f([y]12)
