Hello, AknightwhosayNi!

A group of students where studying how fast a plant was growing.

Once a day they measured the plant. These are the results:

. .

The students created an equation from this information: .

. . where is time in days, is the height of the plant in cm.

How did the students work out 1.6 from this information?

They conjectured that the function is of the form: .

To determine and , use two values from the table.

. . We'll use the first two values . . .

. . Hence, the function (so far) is: .

Therefore, the function is: .
