For instance you have -2(x+7) if you were to rename the problem without parentheses it would be -2•x+7. You multiplied the x+7 in the parentheses by -2 that's outside the parentheses
hope that helped
For this case we have:
Let a function of the form 
By definition, to graph
, where
, we must move the graph of f (x), h units to the left.
We observe that the red graph has the same form as the black graph, but it is displaced "h" units to the left.
It is observed that 
So, if the black graph is given by
, the red graph is given by: 
Answer:

Option A
Y=f(x)=2x find f(x) when x=2
Plug in
f(2)=2(2) =4
Answer
4
