You have also recorded the length of time you spent each week cycling. week 1 week 2 week 3 week 4 week 5 week 6 6 hours  13 hours 11 hours 22 hours 14 hours 9 hours what is the range of the time spent cycling per w?    

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
