Answer:
f'(x)
Step-by-step explanation:
The derivative of the function:

The rule for the product of two functions:
f'(x)
Therefore
g(x)
g'(x)
f(x)
f'(x)
f'(x)
This is an linear equation, so

Answer:
D
Step-by-step explanation:
This is because when making a triangle, the two shortest sides have to add up to be bigger than the biggest side. For example, A would work because if you did 4+6, it would equal 10 which is bigger than the biggest side. B and C add up to something bigger than 6. However, D is different. If you do 2+4, that equals 6. It has to be bigger than six, not equal
