Question

A sunflower is 3 inches tall at week 0 and grows 2 inches each week. Which function(s) shown below can be used to determine the height, f(n), of the sunflower in n weeks?

Answer 1

Simple.....set up your equation....

f(n)=mx+b

It's 3 inches tall...and grows 2 inches each week.

Make your equation...f(n)=2x+3

To make sure it works..plug in some numbers...

Example: x=0

f(n)=2(0)+3

f(n)=3

Thus, you know your equation works.
