Compare the 2 functions that are shown. Function A Time (sec) Distance (meters) 140 10 Function B 20 280 D = 135 30 40 50 420 560 700 Which function has a greater speed, and what is the greater speed? O Function A: 13 meters per second
O Function A; 14 meters per second
O Function B; 13 meters per second
O Function B; 14 meters per second​

Step-by-step explanation:

D

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

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.
