Question

B = { x / -1 £ x £ 3}

Answer 1

Respuesta:

a)     f(x) = x2+x

f(-x) = (-x)2-x = x2-x,  f(x)≠f(-x)

b)    f(x) = x3

f(-x) = (-x)3=-x3,  f(x)≠f(-x)

c)     f(x) = xcos(x)

f(-x) = (-x)cos(-x) = -xcos(x),  f(x)≠f(-x)

d)     f(x) = xsen(x)

f(-x) = (-x)sen(-x) = -x(-sen(x)) = xsen(x),  f(x)=f(-x)

e)     f(x) = x2sen(x)

f(-x) = (-x)2sen(-x) = x2(-sen(x)) = - x2sen(x),  f(x)≠f(-x)
