Let $f(x) = 12x^9 + x$. Find $f(3) + f(-3)$. Help needed in 10 minutes please help!!!!!
f(3)) = 12(3)^9+3
f(-3) = 12(-3)^9-3
Notice how the 2 answers are negative of each other. -a + a = 0
So our answer is 0.

Just put x = 3 into the equation to compute the value
then add the value found when you put x = -3 into the equation.....
12 (3)9 + 3 + 12 (-3)9 -3 = 0
Thanks!!!
