Two exponential functions are shown in the table.
sammy [17]

Based on the table, a conclusion which can be drawn about f(x) and g(x) is that: B. the functions f(x) and g(x) are reflections over the y-axis.

<h3>How to compare the functions f(x) and g(x)?</h3>

In Mathematics, two functions are considered to be reflections over the y-axis under the following condition:

If, f(-x) = g(x).

Evaluating the given functions, we have:

f(x) = 2ˣ

f(-x) = 2⁻ˣ = ½ˣ = g(x).

Similarly, two functions are considered to be reflections over the x-axis under the following condition:

If, -f(x) = g(x).

Evaluating the given functions, we have:

f(x) = 2ˣ

-f(x) = -2ˣ ≠ g(x).

Therefore, we can logically conclude that the two functions f(x) and g(x) are considered to be reflections over the y-axis but not the x-axis.

Select the correct answer.
marishachu [46]

Answer:

M = \log(10000)

Step-by-step explanation:

Given

M = \log(\frac{I}{I_o})

I = 10000I_o ---- intensity is 10000 times reference earthquake

Required

The resulting equation

We have:

M = \log(\frac{I}{I_o})

Substitute the right values

M = \log(\frac{10000I_o}{I_o})

M = \log(10000)
