Answer:
Explanation:
Table I
Given function is,
f(x) =

From the table attached,
For x = 0.827, value of function f(0.827) = 5,
f(0.827) =

Therefore,


0.827[log(b)] = log(5)
log(b) = 0.8452
b =

b = 7
Therefore, function 'f' will be,
f(x) =

For f(x) = 9,
9 =

log(9) = log(
)
log(9) = x[log(7)]
x = 1.129
Table II
Given function is g(x) =

From the given table,
For x = 7, g(x) = 1
1 =


b = 7
Therefore, the function 'g' will be,
g(x) =

For g(x) = 1.318
1.318 =
