What is the base of the natural logarithm function f(x) = ln(x)? Explain how you know.
Zarrin [17]

Answer:

base = e

Step-by-step explanation:

The general log function is defined as

f(x)=\log_a x             .... (1)

where, a is the base of the log function.

The natural logarithm function is

f(x)=\ln x

It can be rewritten as

f(x)=\log_e x              .... (2)

where, e is a constant or Euler's number is:

e ≈ 2.71828183

On comparing (1) and (2) we get

a=e

Therefore, the base of the natural logarithm function is e.

Find the slope of the line that passes through the points (3, 6) and (5, 3).
DanielleElmas [232]

Hello!

To find the slope of the line that passes through the points (3, 6) and (5, 3), we will need to use the slope formula.

Slope formula is \frac{y_{2}-y_{1} }{x_{2}-x_{1}}.

Now, we should assign the given points as x1, y1 or x2, y2. The point (3, 6) can be assigned to x1, y1, and (5, 3) to x2, y2.

Now, substitute the given points into the slope formula.

\frac{3-6}{5-3} =  -\frac{3}{2}

Therefore, the slope of the line is choice A, -3/2.
