Answer from: KenziePaul

1) $f(x)=x^{3}-x^{2}$ is not an odd function

2) $f(x)=x^{5}-3x^{3}+2x$ is an odd function

3) f(x)=4x+9 is not an odd function

Step-by-step explanation:

The function is odd, which satisfies the condition f(-x) = - f(x)

first we check for $f(x)=x^{3}-x^{2}$

Replace x with - x,

$f(-x)=(-x)^{3}-(-x)^{2}$

$f(-x)=(-x)^{3}-(x)^{2}$

we can't write this in the form of f(-x) = - f(x)

so, this is not an odd function

check for $f(x)=x^{5}-3x^{3}+2x$

Replace x with - x,

$f(-x)=(-x)^{5}-3(-x)^{3}+2(-x)$

$f(-x)=-((x)^{5}-3(x)^{3}+2(x))$

f(-x)=-f(x)

so, this is an odd function

check for f(x)=4x+9

Replace x with - x,

f(-x)=4(-x)+9

f(-x)=-4x+9

we can't write this in the form of f(-x) = - f(x)

so, this is not an odd function
