Comparing the two functions, you see that
... g(x) = f(x+7) +9
When x is replaced by x+7, the graph is shifted left 7 units.
When f(x) is replaced by f(x)+9, the graph is shifted up 9 units.
The transformations of f(x) are
- shift left 7 units
- shift up 9 units
The domain is related to the x-value of the function. In this case, the goal of finding the domain is to make sure that the number under the radical sign is positive. The number that makes the function under the radical sign is -2. Hence this is the minimum number and the domain is from -2 to positive infinity.
The border is the perimeter of the scarf.
P= 2(4+1)
= 10
The border of the scarf should be covered by 10 feet.
