Answer with explanation:
Drawing the graph of , y= log x
Domain of log x is all x ≥ 0.
So, y will be always Positive.
⇒Considering the graph of
y= log x-4
When x=1, y= -4
The graph of log x-4 is shifted 4 units down.
⇒And, Considering the graph of
y= log x+4
When x=1, y= 4
The graph of log x+4 is shifted 4 units up.
Option C: ⇒The graph of y=log (x)+4 is the graph of y=log (x) translated 4 units up.

Answer:
Right side towards positive x axis
Step-by-step explanation:
Let us see the basic rule to find the orientation of parabolas.
1. If power if x is 2 and y is 1 , the parabola opens up or down.
2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.
3. If the coefficient of in case 1 is negative it opens downward
4. If the coefficient of in case 2 is negative , it opens left towards negative x axis.
Hence our equation is
here is satisfies the case 2. hence it opens right or left . Also the coefficient of
is positive so it opens up to the right side , that is towards positive x axis.
