\

Observe the table:

\

Lisas temperature during an illness over a $\"\"$ -day period.

\

a.

\

Lisas temperature from $\"\"$ on Monday to $\"\"$ on Monday. \ \

\

Find the average rate of change.

\

Consider the table Lisas temperature $\"\"$ on Monday is $\"\"$ and $\"\"$ on Monday is $\"\"$ .

\

$\"\"$ .

\

$\"\"$ (Formula for rate of change)

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ )

\

$\"\"$ (Simplify) \ \

\

The average rate of change in Lisas temperature is $\"\"$ .

\

$\"\"$

\

b.

\

Lisas temperature from $\"\"$ on Tuesday to $\"\"$ on Wednesday.

\

Find the sign of the rate mean. \ \

\

Find the average rate of change.

\

Consider the table Lisas temperature $\"\"$ on Tuesday is $\"\"$ and $\"\"$ on Wednesday is $\"\"$ .

\

$\"\"$ .

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ )

\

$\"\"$ (Simplify) \ \

\

The average rate of change from $\"\"$ on Tuesday to $\"\"$ on Wednesday is $\"\"$ .

\

The answer is reasonable,Then the number should be negative because her temperature is dropping.

\

$\"\"$

\

c.

\

During which $\"\"$ period was the average rate of change in Lisas temperature the greatest.

\

The average rate of change in Lisas temperature was greatest during Monday $\"\"$ to

\

$\"\"$ is $\"\"$ .

\

$\"\"$

\

a. The average rate of change in Lisas temperature is $\"\"$ .

\

\

b. The average rate of change from $\"\"$ on Tuesday to $\"\"$ on Wednesday is $\"\"$ .

\

c.

\

The average rate of change in Lisas temperature was greatest during Monday $\"\"$ to

\

$\"\"$ is $\"\"$ .
