Concept explainers
a.
To Determine: The interval in which the function is increasing or decreasing.
The function is increasing on the interval of
Given information:
Graph:
From the graph, it can be seen that the graph is increasing on the interval
b.
To Determine: The function is odd, even or neither.
The function is neither even nor odd.
Given information:
Calculation:
A function is even if
Check if
Since
A function is odd if
Multiply
Since
So, the function is neither even nor odd.
c.
To Determine: The extrema of the function, if any.
There are no extrema points.
Given information:
Calculation:
Find the first derivative of the function:
Find the second derivative of the function.
To find the local maximum and minimum values of the function, set the derivative equal to
Set the first derivative equal to
Set the numerator equal to
Since
Convert expressions with fractional exponents to radicals:
Set the denominator in
Solve for
Find the values where the derivative is undefined.
Critical points to evaluate.
Evaluate the second derivative at
The expression is undefined. So, there is no extrema points plotted in the graph.
d.

Thank you so much,arrow_forwardA company estimates that the revenue (in dollars) from the sale of x doghouses is given by R(x) = 12,000 In (0.02x+1). Use the differential to approximate the change in revenue from the sale of one more doghouse if 80 doghouses have already been sold. The revenue will increase by $ if one more doghouse is made. (Round to the nearest cent as needed.)arrow_forward
- The population of bacteria (in millions) in a certain culture x hours after an experimental 20x nutrient is introduced into the culture is P(x) = - 2 Use the differential to approximate the changes in population for the following changes in x. 8+x a. 1 to 1.5 b. 3 to 3.25 a. Use the differential to approximate the change in population for x=1 to 1.5. Between 1 and 1.5 hours, the population of bacteria changes by million. (Round to three decimal places as needed.)arrow_forwardThe demand for grass seed (in thousands of pounds) at price p dollars is given by the following function.

- A manufacturer of handcrafted wine racks has determined that the cost to produce x units per month is given by C = 0.3x² + 7,000. How fast is the cost per month changing when production is changing at the rate of 14 units per month and the production level is 80 units? Costs are increasing at the rate of $ (Round to the nearest dollar as needed.) per month at this production level.arrow_forwarddy Assume x and y are functions of t.

A tank with a capacity of 650 gal. originally contains 200 gal of water with 100 lb. of salt in solution. Water containing 1 lb. of salt per gallon is entering at a rate of 4 gal/min, and the mixture is allowed to flow out of the tank at a rate of 3 gal/min. a. Find the amount of salt in the tank at any time prior to the instant when the tank begins to overflow (650 gallons). b. Find the concentration (in pounds per gallon) of salt in the tank when the tank hits 400 gallons. D.E. for mixture problems: dv dt=11-12 dA A(t) dtarrow_forward
