Question

symmetry of F(x)= x^2-4/x^2-2x

Answer 1

what you need to do ?

Answer 2

find the symmetry of the function given

Answer 3

can you simplifie it ,yes ?

Answer 4

(x+2)(x-2)/x(x-2)

Answer 5

and ... ?

Answer 6

thats all i can simplify

Answer 7

yes you can yimplifie it now ,yes ?

Answer 8

how you think what mean symetry of f(x) ?

Answer 9

oh (x+2)/x

Answer 10

i know if i plug in f(-x)= i get -x-2/-2
which is the negative of the function but i dont know what to do after

Answer 11

ok

but can you say me what mean symmetry of f(x)= x ,for example ?

Answer 12

you have not an example inside your math book ?

Answer 13

if f(-x) = f(x) for all x in D, that is, the equation of the curve is unchanged when x is replaced by -x, then f is an even function and the curve is symmetric about the y axis
if f(-x) = -f(x) for all x in D, then f is an odd function and the curve is symmetric about the origin
