What is the average rate of change for the quadratic function from x=-4 to x=8?

1 answer:

3 0

Just do

(f(8)-f(-4))/(8-(-4))

f(8)=-2
f(-4)=-74

average rate of change is (2-(-74))/(8-(-4))=(2+74)/(8+4)=76/12=19/3

the average rate of change is 19/3

11 9/10 First you have to add 10 3/5 and 12 1/2. You get 22 11/10. That is an improper fraction. There are one 10 in 11. So you add 1 1/10 to 22. You get 23 1/10. Now you have to subtract 23 1/10 and 35. You get 11 9/10
