A wire meters long is to be cut into two pieces. One piece will be shaped as an equilateral triangle, and the other piece will be shaped as a circle.
Part (a): Express the total area Aenclosed by the pieces of wire as a function of the length x of a side of the equilateral triangle.
Part (b): What is the domain of A?
Part (c): Graph . For what value of xis Asmallest?
Exploration Graph , and on the same screen. What do you notice is the same about each graph? What do you notice that is different?
In Problems 7–18, match each graph to one of the following functions:

Exploration Graph . Then on the same screen graph . What pattern do you observe? Now try and . What do you conclude?
Exploration Graph . Then on the same screen graph . Could you have predicted the result?
