The graph of the function y=tan(x) was horizontally stretched so that its period became 10. which is the equation of the
transformed function?
y = tanto
o y-tan()
y=tan(5x)
o y=tan(10x)

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

i would guess 26 because this isnt a sequential pattern or its to short to know
