At 5: 00 p.m., the outside temperature was –9.2°c. by 10: 00 p.m., the outside temperature had dropped 4.5°c. what was the outside temperature at 10: 00 p.m.?

6 goes with [-4,-2]

1 goes with [-2,1]

2 goes with [-3,1]

4 goes with [-4,0]

Step-by-step explanation:

x     f(x)

-----------

-4    -12

-3     -5

-2      0

-1      3

0      4

1        3

Before I continue, you need to know what f(a) means. f(a) means find x=a and the value that corresponds to it is f(a).

That is f(-4)=-12 from row 1.

That is f(-3)=-5 from row 2.

That is f(-2)=0 from row 3.

That is f(-1)=3 from row 4.

That is f(0)=4 from row 5.

That is f(1)=3 from row 6.

Average rate of change on is given by the formula:

or you could use .

So the average rate of change on [-4,-2] is given by

The average rate of change on [-2,1] is given by

The average rate of change on [-3,1] is given by

The average rate of change on [-4,0] is given by
