Supreme court ruled in the 1857 Dred Scott v. Sandford decision that enslaved African Americans were not citizens. In 1866 congress proposed the Fourteenth amendment. The amendment had the effect of overruling the Dred Scott decision. This is an example of a check of the judicial branch by the ... A. Executive Branch
B. Legislative Branch
C. Judicial Branch
D. Presidential Branch

I believe the answer is D

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
