What is the rule for the reflection? M(-5,4)
M'(5 4)
4
Ory-axis(x, y) + (-x, y)
Ory-axis(x, y) = (x, -y)
Orx-axis(x, y) - (x, y)
Orx-axis(x, y) = (x, -y)
(-6,2) N(-3,2)?
N'(32
L'6,2
2.

The rule of reflection over y-axis is  (x,y)→(-x ,y)

M(-5,4) →M¹( 5 , 4)

N(-3,2) →N¹(3 ,2)

L(-6,2) →L¹( 6,2)

Step-by-step explanation:

Explanation:-

Type of transformation                     change to co-ordinate point

Reflection over x-axis                          (x,y)→(x ,-y)

Reflection over y-axis                          (x,y)→(-x ,y)

Given co-ordinate is M(-5,4)

The reflection over y-axis is  (x,y)→(-x ,y)

M(-5,4) →( 5 , 4)

N(-3,2) →(3 ,2)

L(-6,2) →( 6,2)

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.
