From -co to 0, the derivative is y=-2x and its domain is (-co,4]. Then y=-(x-2)/2 + 6 from (4,co)
the assumption being that M is the midpoint of AC, if that's the case, then M cuts AC into two equal halves, namely then AM = MC

Answer:
Solving the inequality
we get 
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality
and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

Adding 2 on both sides

Now, we will divide 3 on both sides

So, we get x < 2
Solving the inequality
we get 
Option D is correct option.
