Question

Please help! Determine whether the graph of of the equation is symmetric with respect to the x-axis, y-axis, and / or the origin.

1.) y=(x+8)(x-9)
2.) y=(x-1)(x-4)

Answer 1

A function is symmetric about the y axis (sometimes called an even function)
when y(x)=y(-x)

Answer 2

I got none for both but I am not sure.

Answer 3

does anyone know and could help me?

Answer 4

yeah i guess neither of them are symmetric

Answer 5

what method did use, @some_someone,

Answer 6

umm i used the one where for the y-axis : y(x)=y(-x)
and x-axis: y(x)=-y(x)

Answer 7

w8 i m telling

Answer 8

see fr the equation u hav listed neither of them is symmetric about y and x axis

Answer 9

nw check fr origin :put -y and -x in place of y and x respectively in the equation u hav listed

Answer 10

yes none of them are symmetric. Am i right?
for orgin i also got none. but i am not sure?

Answer 11

while putting -x and -y r u getting the same equations? check it out n tell me asap

Answer 12

u r nt getting the same equation so fr the eqn. 1 it is not symmetric about origin

Answer 13

check fr equation 2

Answer 14

equation 2 also not symmetric about origin

Answer 15

yes, i got that for both. i also got no x and y-axis of symmetry for both. am i right
for that?
