Completing the square gives
At the point on the graph along the axis of symmetry, the squared term vanishes, so that when 
, we have 
. So
Answer:
Developed Length
Step-by-step explanation:
A developed length is the length along the centre line of a circular shape.
From the question, the degree of bend is 90°
Also, from the question; the length of an arc of 1 quadrant.
1 quadrant = 90°
And the degree of bend = 90° (from the question)
So, it's safe to say 1 quadrant = the degree of bend = 90°
A small change in 90° will move change the quadrant to another quadrant.
So, at exactly 90° (or other multiples of 90° which are 180°, 270° and 360°), it is at its developed length.
