Question

When an experiment began, the temperature of a substance was −5°C . During the experiment, the temperature rose exponentially. The scientist will sketch a graph of the situation, where x represents the time after the experiment began, and y represents the temperature of the substance at that time.

The scientist will only sketch the graph in the quadrant or quadrants for which it makes sense to.

In which quadrant or quadrants will the scientist sketch the graph?



Quadrants I and IV only
Quadrants I, II, III, and IV
Quadrants I and II only
Quadrant I only

Answer 1

If the temperature is rising from -5 on the x-axis, then the sketches would only appear in Quadrants II and I, as it rose higher and higher. Hope I helped!

Answer 2

In which quadrant or quadrants will the scientist sketch the graph?

Option I: Quadrants I and IV only

Explanation:

x represents the time after the experiment began. The experiment began at x=0, and the time is a positive quantity, then x>=0. The x is positive in the Quadrants I and IV.

y represents the temperature of the substance at that time. When the experiment began, the temperature of the substance was −5°C (negative):

y < 0. y is negative in Quadrants III and IV

During the experiment, the temperature rose exponentially, then the temperature must increase and take positive values. y is positive in Quadrants I and II.

Like x is positive (Quadrants I and IV) and y is negative (Quadrants III and IV) and positive (Quadrants I and II), the scientist will sketch the graph in Quadrants I and IV only
