Question

is the function f(x)=3x^4+4x+8 even odd or niether. show proof

Answer 1

if f(-x) = f(x); its even

if f(-x) = -f(x) it is odd

if it aint those, then its neither

Answer 2

f(x)=3x^4+4x+8

f(-x)=3(-x)^4+4(-x)+8
= 3x^4 - 4x + 8
f(-x) NOT= f(x); so it aint even

Answer 3

f(x)=3x^4 +4x +8

-f(x) = -3x^4 -4x -8

f(-x) NOT= -f(x) ; it aint odd

its got to be neither

Answer 4

thank u

Answer 5

yep :)
