Answer: The required expression for -g(x) is -x+6.
The answer for the second one is 0
Explanation:
-g(x) is = -(x-6)
if you distribute the equation will be -x+6
the second question is g(x) + (-g(x))
if you add a positive with a negative it cancels out or equals 0
g(x) + (-g(x))= 0 and g(x) - g(x)) = 0
