The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on the parabola. Which equation can be used to model the image of the lens?y = -1/5 (x – 2)(x + 3)
y = -1/3(x – 2)(x + 3)
y = -1/2 (x + 2)(x – 3)
y = 1/4 (x + 2)(x – 3)

Answer:
The greatest possible error for the measurement 3.2 cm is 0.05 cm.
Step-by-step explanation:
We have given that,
Bruce measured a buckle as 3.2 cm using the ruler
We have to find,
What is the greatest possible error?
Solution is given by,
The greatest possible error is defined as the error is half of the measuring unit.
Bruce measured a buckle as 3.2 cm using the ruler.
The measuring unit is nearest tenth of a cm or 0.1 cm.
The greatest possible error is half of 0.1.
i.e.
Therefore, The greatest possible error for the measurement 3.2 cm is 0.05 cm.
