The number of tickets sold each day for an upcoming performance of​ Handel's Messiah is given by N= -0.4x^2+9.6x+14, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that​ day?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
