To complete the tables we need to evaluate both functions in the correspondent values.
For the first table the missing value is 6
For the second table, the missing value is 1.585
How to complete the tables?
In the first table, we can see that:
f(x) = b^x
We can see that:
f(-1) = 0.5= b^-1 = 1/b
Now we can solve this for b.
b = 1/0.5 = 2
Then to complete the table, we need to evaluate this on x = 2.585
f(2.585) = 2^2.585 = 6
This is the value that goes on the first table.
For the second table, the function is:
g(x) = log_b(x) = ln(x)/ln(b)
We already know that b = 2, then:
g(x) = ln(x)/ln(2).
To complete the value, we need to evaluate in x = 3, then we have:
g(3) = ln(3)/ln(2) = 1.585
This is the value that goes on the second table.
