Question

# The graph shows the temperature between noon and midnight in City A on a certain day.

The table shows the temperature, TT, in degrees Fahrenheit, for hh hours after noon, in City B.

1.Which city was warmer at p.m.?

2.Which city had a bigger change in temperature between p.m. and p.m.?

3.How much greater was the highest recorded temperature in than the highest recorded temperature in City A during this time?

4.Compare the outputs of the functions when the input is 3 .

Hint:

### First, we need to compare the temperature at a certain time, which is clearly visible from the given data. Next, we need to find the change in temperature between different times of the day and the highest recorded temperature in both cities. Finally, we need to find the temperature of both the cities at 3:00 PM. We need to correctly check the graph for the values of the temperature.

## The correct answer is: graph and table correctly to find the correct answer.

*Step by step solution:*

1.

From the graph, we can observe that

The temperature in city A at 4:00 pm = 57 F

From the table, it can be seen that

The temperature in city B at 4:00 PM = 62 F

Comparing the above two values, we get that city B was warmer at 4:00PM

2.

For city A:

Temperature at 1:00 PM = 50.5 F (approx)

Temperature at 5:00 PM = 58 F

Change in temperature = (58-50.5=) 8.5 F

For city B:

Temperature at 1:00 PM = 82 F

Temperature at 5:00 PM = 58 F

Change in temperature = (58-82=) -24 F

Thus, there is a bigger change in temperature between 1:00 PM and 5:00 PM in city B.

3.

From the graph,

The highest recorded temperature in City A = 59 F

From the table,

The highest recorded temperature in City B = 82 F

Hence, the highest recorded temperature in City B is greater than the highest recorded temperature in City A by (82-59) F = 23 F

4.

Assuming that the input is the time after noon, we need to find the output which is the temperature at that time.

Input is given to be 3

So,

Temperature in city A at 3:00 PM = 54.5F (approx)

Temperature in city B at 3:00 PM = 75 F

Here, we just need to read the given question carefully and understand each and every term. We need to interpret the graph and table correctly to find the correct answer.
