Simplify the equation below

- (x^5)/96

Step-by-step explanation:

16^0 is one, y^5 cancels each other out.

To reflect over the x axis (horizontal axis), multiply f(x) by -1. Use parenthesis to indicate -1 is multiplied by all of f(x) and not just a portion of it.

g(x) = -1*f(x)
g(x) = -1*( f(x) )
g(x) = -1*( 3x+12) 
g(x) = -1*(3x) - 1*(12)
g(x) = -3x - 12

Don't forget to distribute the negative to EVERY term inside the parenthesis. 

So the final answer is choice D.
