Answer:
It's odd.
Explanation:
A function is odd when <span><span>f<span>(−x)</span></span>=−<span>f<span>(x)</span></span></span>
<span><span>f<span>(−x)</span></span>=6<span><span>(−x)</span>3</span>−2<span>(−x)</span></span>
<span>=−6<span>x3</span>+2x</span>
<span>=−<span>(6<span>x3</span>−2x)</span></span>
<span>=−<span>f<span>(x)</span></span></span>
Thus, the function is odd.
If a function is odd, then it is symmetric over the x-axis.
Notice that





so that for each power of 2, there is a pattern of period 4. This means that for integers

, each of

,

,

, and

have the same units digit.
We can write

, and since

, it follows that

and

share the same units digits. So the units digit of

is 8.
75% ended the race
25-18=6
6 goes into 24 4 times so it is 25% that did not finish
100%-25%=75%
So 75% finished the race
Hmm...I tried to divide 29 by 14, and I got 2.07142857143.... Does it let you round the decimal..?
