The height of a tree in feet over x years is modeled by the function f(x).
SVEN [57.7K]
The following statements are true:
The tree grows approximately 7 feet between years 5 and 7; 
the tree stops growing at around 30 feet

In graphing the function, we see that the initial value, when x = 0, is 1 ft, not 2.
Additionally, we can see the values as the height increases; when the tree hits 15 feet, it continues to grow at around 1.5 feet every 0.4 years until it hits around 25 feet tall.  Then it begins to slow down.
