2. Find the slope, or rate of change, represented in the table below. -1 x 0 1 2 3 Y-8 3 14 25 36​

11

Step-by-step explanation:

Given the data:

X: - 1 _ 0 _ 1 _ 2 _ 3

Y: -8 _ 3 _ 14 _ 25 _36​

Slope = Rise / Run

Rise = y2 - y1 = 36 - (-8) = 36 + 8 = 44

Run = x2 - x1 = 3 - (-1) = 3 + 1 = 4

Slope = 44 / 4

Slope = 11

Rate of changeb/ slope = 11

b

step-by-step explanation:

b

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.
