Question

Which ideas about functions do you think might be the most helpful to you in your day-to-day planning?

Answer 1

Answer:

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 $y = 20x$ 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).
