Solution

Let's analyze the problem and solve it step by step.

The problem provides two functions:

  1. f(x)=bxf(x) = b^x in Table I.
  2. g(x)=logb(x)g(x) = \log_b(x) in Table II.

Both functions involve a base bb, which is the same positive constant for both tables.

We need to fill in the missing values in the tables.

Step 1: Relating the two functions

  • Exponential Function: f(x)=bxf(x) = b^x.
  • Logarithmic Function: g(x)=logb(x)g(x) = \log_b(x), which is the inverse of the exponential function.

Thus, if f(x)=bxf(x) = b^x, then g(x)=logb(f(x))=xg(x) = \log_b(f(x)) = x, and vice versa.

Step 2: Analyze the given data

We'll begin by trying to deduce the base bb using the known values from Table I and Table II.

Table I (for f(x)=bxf(x) = b^x):

  • f(0.585)=1.5f(0.585) = 1.5
  • f(1)=?f(1) = ? (missing value)
  • f(3)=8f(3) = 8
  • f(3.322)=10f(3.322) = 10

Table II (for g(x)=logb(x)g(x) = \log_b(x)):

  • g(1.5)=0.585g(1.5) = 0.585
  • g(2)=1g(2) = 1
  • g(2.322)=?g(2.322) = ? (missing value)
  • g(5)=2g(5) = 2
  • g(3)=3g(3) = 3

Step 3: Determine bb

From Table I, we have:

  • f(3.322)=10b3.322=10f(3.322) = 10 \Rightarrow b^{3.322} = 10. Taking the logarithm: b=1013.3222.154b = 10^{\frac{1}{3.322}} \approx 2.154 So, the base b2.154b \approx 2.154.

Step 4: Fill in missing values

Now that we know b2.154b \approx 2.154, we can use it to find the missing values.

For Table I:

  1. f(1)=b1=2.1541=2.154f(1) = b^1 = 2.154^1 = 2.154.

For Table II:

We know g(x)=logb(x)g(x) = \log_b(x).

  1. g(2.322)=log2.154(2.322)1.252g(2.322) = \log_{2.154}(2.322) \approx 1.252 (rounded to 3 decimal places).

Final Tables:

Table I:

\hline x & f(x) = b^x \\ \hline 0.585 & 1.5 \\ 1 & 2.154 \\ 3 & 8 \\ 3.322 & 10 \\ \hline \end{array}$$ #### Table II: $$\begin{array}{|c|c|} \hline x & g(x) = \log_b(x) \\ \hline 1.5 & 0.585 \\ 2 & 1 \\ 2.322 & 1.252 \\ 5 & 2 \\ 3 & 3 \\ \hline \end{array}$$ Let me know if you would like further details on any step or calculation! --- ### Related Questions: 1.
