Find the width that maximizes the area of the rectangle. O cannot be determined 20 ft 25 ft 50 ft\fQuestion 7 (5 points) Given the graph of some function f (x), we can obtain the graph of g(x) = -f(x+ 8) by. O shifting f right 8 units, then reflecting that graph over the X-axis. O shifting f left 8 units, then reflecting that graph over the y-axis. O shifting f left 8 units, then reflecting that graph over the X-axis. shifting f right 8 units, then reflecting that graph over the y-axis
