Match with the picture a.)x> (greater than or equal to)b.)x< (less than or equal to)c.)x< -2d.)x> -2also don't mind if the words in parentheses are wrong i'm not that great at math

see explanation

Step-by-step explanation:

A number line with an open circle denotes > or <

A number line with a closed circle denotes ≥ or ≤

The sign of the inequality will depend on the direction of the arrow

To the right denotes > or ≥

To the left denotes < or ≤

first diagram is x > - 2

The second diagram is x ≥ - 2

The third diagram is x ≤ - 2

The fourth diagram is x < - 2

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.
