Answer:
a. -2 b. -2 c. -1 d. 4 e. -3 f. 0
Explanation:
The average rate of change formula is:
a.
We need to find the rate of change for x = -3 to x = -2 so we look on the graph to find y.
At x = -3 it look like y = 0 so
At x = -2 it looks like y = 2
Now we can just plug everything in to the rate of change formula.
= -2
So for a. our rate of chage for the given interval is -2
b.
Now that you have the formula we don't need to explain each time.
-2
2
1
- 4
= -2
c.
0
-3
1
- 4
= -1
d.
1
-4
2
0
= 4
e.
-1
0
0
-3
= -3
f.
-1
0
2
0
= 0
