A function is odd when symmetric with the origin, f(-x) = -f(x).
Odd functions will have odd exponents! :-) 
although the line 3x - 1 has an odd exponent of 1, it isn't because it's not symmetric, doesn't give -f(x). 

Odd function:  f(x) = 0.8x³

Next problem asks for the degree of the function, this is the power of x.When x = -2 the output value h(x) = -8
Do you see that the output values are always negative? This suggests it's either an odd exponent or being multiplied by a negative number.
(-2)³ = -8
(-1)³ ≠ -2
* function must be multiplied by -2. Then it becomes a basic parabola

f(x) = -2x²

power/degree is 2
