How can you represent Pattered from every day life by using tables, expressions and graphs

For example, we can look at the variations of temperature by the time of the day.

We can write it in a two column table, where we can write the hour in one column and the temperature in the other column.

This will show us a relationship between them that is oscillating.

We can graph this and have something like:

Then, we can adjust a function to that, like a trigonometrical function that can model this relation between temperature and hour of the day. There you wil have an expression for this pattern.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
