Point (4,8) reflected across the Y axis

Point (4,8) reflected across the y-axis is (-4,8).

Step-by-step explanation:

Point (4,8) reflected across the y-axis is (-4,8).

When reflecting a pair of numbers across the y-axis, the x-axis changes to its opposite.

Thus, in this case, 4 would change to -4.

I hope this helped!!

answer: r there any options?

step-by-step explanation:

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.
