Answer:
8.86 > 8.65
Step-by-step explanation:
Let y = f(x)
y = (1 + e^x)/(1 - e^x)
Exchange places with x and y.
x = (1 + e^y)/(1 - e^y)
Now solve for y.
y = log[(x + 1)/(x - 1)]
Replace y with the inverse notation.
f^(-1) x = log[(x + 1)/(x - 1)]
Done!
Answer:
The first one
Step-by-step explanation:
A direct variation is when x and y are multiplied or divided by the same number. For example, in the first one y is always 8 times x. But, in the 2nd 3rd and 4th one that is not the case.
Hope this Helps!!! :)

From the standard normal tables, obtain
P(z<1.95) = 0.9744
P(z<0.37) = 0.6443
P(z<1.32) = 0.9066
P(z<1.82) = 0.9656
P(z<1.05) = 0.8531
P(z<2.05) = 0.9798
P(z<0.03) = 0.5120
P(z<0.53) = 0.7019

-------------- ---------------------------------------
a. 0 - 1.95 0.9744
b. 0 - 0.37 0.6443
c. 1.32 - 1.82 0.9656 - 0.9066 = 0.0590
d. 1.05 - 2.05 0.9798 - 0.8531 = 0.1267
e. 0.03 - 0.53 0.7019 - 0.5120 = 0.1899
