1.6 : 4
1.6 is also equal to 8/5
therefore,
8/5 : 4
(8/5)/4
**get the reciprocal of the denominator (4) which is equal to 1/4**
(8/5)*(1/4)
(8/4)*(1/5)
2*(1/5)
2/5
two fifth is the answer
The answer think will be x=4/7
Or 4-7x
The average rate of change is (total change in f(x))/(total change in x) so
r=(f(6)-f(2))/(6-2)
r=(36-6-4-4+2+4)/4
r=7
