I believe the correct answer among the choices listed above is option A. Cars entering our field of vision from the side require the use of peripheral vision. This is the side vision. The vision that occurs outside the very center of gaze. Hope this answers the question.
Answer:
The temperature is staying the same. In the graph when it shows solid/liquid and liquid/gas, the temperature stays the same until it changes. This is because it reached it's melting point/vaporizing point. For example, a solid gets heated up, it then reaches it's melting point but it can't go higher than that because it isn't fully a liquid yet, once it's a liquid it will then continue to rise in temperature.
I don't think I put enough detail into that explanation but I hope this helps your problem.
(x-3)² = (x-3)(x-3)
= x² - 3x - 3x + 9
= x² - 6x + 9
