Ayogurt with 1 topping is sold for $3.75. additional toppings can be added for $0.65 cents each. if y represents the total cost and x represents the total number of toppings added, which function rule describes this pattern? a. y = 3.75(x - 1) + 0.65 b. y = 3.75 - 0.65(x + 1) c. y = 3.75 + 0.65x d. y = 3.75 + 0.65(x - 1) is d the answer?

Yes, you are correct D is the right answer.

yes

step-by-step explanation:

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.
