2 x 103 = 206, 8 x 105 is 840.
840 is roughly 4.08 times greater than 206.
So 4*10^7 is _ times greater then 4*10^3
So, 4000, 40000000
So 10000 times greater

For a function to be odd f(-x)=-f(x).
1) putting x as -x
f(-x)= -x^3+x^2 = -f(x)
Thus, this is an odd function.
2) Following the same procedure,
f(-x)= -x^5+3x^3-2x =-f(x)
Thus, this is an odd function.
3) Again,
f(-x)= -4x-9 = -f(x)
This also is an odd function.
Hope this helps :)
