I need help on my math! If you could help on all of them I will mark brainliest!!

The instructions say for set A through F write

The set is a relation but not a function

Function if the set is both a relation and function and

neither of the set is not a relation

Vas Happenin' ?! :D

A = neither

B = function

C = relation

D = function

E = Function

F = function

Step-by-step explanation:

For f(x): (x, y) to be a function

For f(x) to be a relation

it's neither a function nor a relation.

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.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
