Find a formula for the described function. A rectangle has perimeter 8 m. Express the area A of the rectangle as a function of the length, L, of one of its sides. A = m^2 State the domain of A. (Assume the length of the rectangle is longer than its width. Enter your answer in interval notation. If the point (7, 1) is on the graph of an even function, what other point must also be on the graph?
