Answer:
Turning point has coordinates 
Step-by-step explanation:
Gandalf the Grey started in the Forest of Mirkwood at a point P(3, 0) and began walking in the direction of the vector
The coordinates of the vector v are (-3,2). Then he changed the direction at a right angle, so he was walking in the direction of the vector
(vectors u and v are perpendicular).
Let B(x,y) be the turning point. Find vectors PB and BQ:

Note that vectors v and PB and vectors u and BQ are collinear, so

Hence

Now solve the system of two equations:

Multiply the first equation by 3, the second equation by 2 and add them:

Substitute it into the first equation:
Turning point has coordinates 
Answer:

Step-by-step explanation:
Given
The attached graph
Required
Determine the range of the graph
First, we list out the coordinate of each point on the graph:
The points are:

A function has the form: (x,y)
Where
y = range:
From the coordinate points above,

Order from least to greatest"

Hence, the range are:
