Three functions are given below: f(x), g(x), and h(x). determine the axis of symmetry for each function. show all calculations.  f(x) = -2(x − 4)2+ 2g(x) = 5x2− 10x + 7h(x) is shown on the graph belowsomeone me, i would greatly appreciate it : -)

Ithink is the abswer b

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
