Suppose you take a straight piece of wire measuring 20 cm and cut it to make two pieces. You then take one piece and make it into a square, and the other piece and make it into a circle, like in the following picture: 20 cm- 20-x Write a function, 4(-x), that gives the total area of the circle and the square you A(x) а. make in this scenario. b. What is the domain of 4(.x)?

What is the correct answer

what is the domain and range of this in interval notation ?
