The advertising and sales model of a company is given by the function s = 2t2 + 100, where t is time in months and t ≥ 0. if advertising is delayed by a month, which type of transformation will occur to this model?

a.
shift along the x–axis

b.
shift along the y–axis

c.
reflection through the y–axis

d.
reflection through the origin

answer: it is a.   shift along the x–axis

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 believe it is b and c. (side note, i got the same computer from k-12 lol i’m in 8th grade and this is my first year, will it get
