answer: option d is correct .
in order to find the same attendance we set both equation equal
8x+191 = -x^2+26x+126
simplifying equation ,we get
(x-5) (x-13) = 0
x =5 or x =13
therefore on 5th day and 13th day both plays attendance is same
and it is obtained by plugging x = 5 in and x =13 in either of the equation.
for x = 5 ,
y = 8(5) +191 = 40+191 = 231
for x = 13
y = 8(13)+191
therefore option d is correct
options a and d are right.
the given function is of the above form
we have here a=1/4 : b=1 : p = -pi/3: and k=-1
hence we have an amplitude of 1/4, horizontal shift of pi/3 to the right,vertical shift of 1 unit down and vertical shrink of 1/4
hence the correct choices would be
1) it has amplitude 1/4
d) horizontal shift of pi/3 to the left
other options are false
