(a)
To find: The inverse of the function
The inverse of the function is continuous.
Given information
If a one-to-one function is continuous in its domain, then its inverse function is also continuous. |
We can prove it by an example let
It can be seen that both f(x) and g(x) are continuous. The graph of
(b)
To find: The inverse of the function
The inverse of the function is is one one.
Given information
We can prove it by an example let
The inverse of the function passes the vertical and horizontal line test so it is one − one.
(c)
To find: The inverse of the function
The inverse of the function is odd.
Given information
If a one-to-one function is continuous in its domain, then its inverse function is also continuous. |
We can prove it by an example let
As it is clear from the graph that inverse of f(x) is symmetrical about the origin and it is odd therefore
(d)
To find: The inverse of the function
The inverse of the function is increasing.
Given information
If a one-to-one function is continuous in its domain, then its inverse function is also continuous. |
We can prove it by an example let
It is clear from the graph for

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. D(p) 3p³-2p² + 1460 Use the differential to approximate the changes in demand for the following changes in p. a. $4 to $4.11 b. $6 to $6.19arrow_forwardLet the region R be the area enclosed by the function f(x) = 3 ln (x) and g(x) = 3 x + 1. Write an integral in terms of x and also an integral in terms of y that would represent the area of the region R. If necessary, round limit values to the nearest thousandth.

- 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. Evaluate for 2xy -3x+2y³ = - 72, with the conditions dt dx dt = -8, x=2, y = -3. dy dt (Type an exact answer in simplified form.)arrow_forwardConsider the sequence below: 1 1 1 (a) Express this sequence as a recurrence relation (b) Express this sequence in the form {a}=1 (c) Does this sequence converge or diverge?

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
