b) Find h- (6). 10 points ] On a quiz is the following question: Determine if the function p(x) =-10x + x is even, odd or neither. Rodney answered it like this: Draco answered it like this: p(-x) =-10(-x)'-x p(-x) =-10(-x) -x =10x'-x =10x' -x = -(10x -x) Since p(-x) # p(x), the function is neither. =-P(x) Since p(-x) = -p(x), the function is odd. Who is correct? Rodney? Draco? Both? Neither? Are there any errors in any of the student work? Give a full explanation of your judgment for both of the students' work
