Answer:
The inverse f-1(x) = (2 - x)/4 + 1.
Step-by-step explanation:
Let y = -4 /(x - 1) + 2
-4/(x - 1) = y - 2
x - 1 = (y - 2) / -4
x = -(y - 2)/4 + 1
x = (2 - y)/ 4 + 1
Now replace x by f-1(x) ( the inverse) and y by x:
f-1(x) = (2 - x)/4 + 1.
Answer: 0.6/h
Step-by-step explanation:
6.15-3.75= 2.4
2.4/4= 0.6
Answer:
a
Step-by-step explanation:
Answer:
Thus the answer is : B (122)
Step-by-step explanation:
The time series was estimated using a time series with 20 time periods.
And the forecasted value for time period t after 20 time periods is 120 + 2t
For time period 21, the value of t is 1.
Hence, the forecasted value for time period 21 is 120 + 2*1 = 122
Thus the answer is : B (122)
