The maximum level of intensity for passion is 8
The maximum level occurs at 4 years
Step-by-step explanation:
To answer the questions in the problem we need to know how to read graphs. In this case we have a graph of years vs intensity of emotions in a relationship.
The time is in the x-axis (the horizontal one) and the intensity in the y-axis (the vertical one)
We're are looking at the intensity of the passion over time. In the graph, the passion over time is represented by the red dotted line.
To know the maximum value, we need to look the value of passion intensity that is above all the rest. We can see that this value corresponds to an intensity of 8, when the passion peaks is at an intensity of 8 indicated by the vertical axis.
To know the time the peak occurs, we need to look at the value in the x-axis that correspond to the peak. In this case, we can see that when the passion is at an intensity of 8, it corresponds to value 4 in the x-axis
