The answers b. you’d plot the points onto the graph. so there’s 1 one time, 2 one time, 3 two times, etc. cross out one number from each end until you reach the middle or middle two numbers. it’s not two in this case and the middle number is 4, which is the median. then it’s symmetrical because it’s the same on both sides after you plot it. if you fold it in half it’d be even. range is highest number - lowest, so 7 - 1 = 6

(1/x + 1)^2 + 6 (1/x + 1) +5
