Hopefully easy for yall The number of toys sold per month can be modeled by f(x) = 3x4 + 2x3 + 5x + 10, where x represents the number of months since June. Let g(x) = f(x) + 3. Which of the following gives the rule for g and the correct explanation of the meaning of the transformation in terms of monthly toy sales? 3x4 + 2x3 + 5x - 7 vertical shift 3 units down decrease of 3 units per month 3x4 + 2x3 + 5x + 3 vertical shift 3 units up increase of 3 units per month 3x4 + 2x3 + 5x + 7 vertical shift 3 units down​

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.

if you need just tell me and i will come to the rescue.
