The K value is often found at the end of the formula for instance, f(x) = log(x) +k. The K value moves the graph up or down depending on if it is negative or positive.

Answer:

The correct option is (B) The "k" value moves the graph up or down.

Step-by-step explanation:

Consider the provided function:

f(x)=log(x)

The graph of the provided function is shown in figure 1.

From figure 1, it can be seen that the domain of the function is all positive real numbers and not defined for the negative values.

The logarithmic function can be shift <em>h</em> units horizontally and <em>k</em> unit vertically for the equation:

f(x)=log_{b}(x+h)+k

Horizontal shift:

For <em>h</em> > 0, graph shift <em>h</em> units left and for <em>h</em> < 0, graph shift <em>h</em> units right.

For better understanding refer to the figure 2.

Vertical shift:

For <em>k</em> > 0, graph shift <em>k</em> units up and for <em>k</em> < 0 graph shift <em>k</em> units down.

For better understanding refer to the figure 3.

Hence, the correct option is (B) The "k" value moves the graph up or down.

Suppose a manufacturer sells a product as $2 per unit. If q units are sold, (a) write the total revenue function, (b) and find t
Ahat [919]

Answer:

We are given that  a manufacturer sells a product as $2 per unit.

Quantity = q units

So, Total revenue = \text{Cost per unit} \times quantity

Total revenue = 2q

So, the total revenue function is  2q

Marginal revenue is the derivative of the revenue functions

So, Marginal revenue = \frac{dR}{dq} =2

The marginal revenue function is 2

The constant marginal revenue function mean that the revenue earned by the addition of the output is constant.

Taryn bought 12.6 gallons of gasoline. There are approximately 3.8 liters in 1 gallon. Which measurement is closest to the numbe
Alina [70]

Answer:

<h2> Amount in liters is 47.9 liters</h2>

Step-by-step explanation:

The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer

Step one:

Given data

Taryn Bought 12.6gallons of gasoline

1 gallon of gasoline is  3.8 liters

We want to convert from gallons to liters

Step two:

----if 1 gallon has 3.8 liters

then 12.6 gallons will have x liters

cross multiply we have

x= 12.6*3.8

x=47.88 liters

Hence the estimated amount in liters is 47.9 liters
