- For the function (x)=1/(x+1) is f(x)^-1= (1/x)-1 the inverse? If so, please show how!arrow_forwardIf y varies inversely as the 4th power of x and y = 5when x = -1, what is y when x = 0.5?arrow_forwardHello, I need help with inverse functions. Here is the question from the textbook. If g(x) = 3 + x + ex, find g-1(4).arrow_forward
- a) find domain and range of f(x) b) find domain and range of f-1(x) c) find explicit formula for the inverse of the equation, f^-1(x)arrow_forwardGiven f(x) =x/x-2 , find a formula for the inverse function. SHOW WORKarrow_forwardAre these functions inverses of each other? f(x) = 3x - 12 g(x) = 1/3 x + 4 yes or no ? if f(x) = x³ - 27 what type of function would g(x) likely be in order to be the inverse?arrow_forward
- The inverse notation f−1 used in a pure mathematics problem is not always used when finding inverses of applied problems. Rather, the inverse of a function such as C=C(q) will be q=q(C). The following problem illustrates this idea. In a certain country, the following function represents the income tax T (in dollars) due for a person whose adjusted gross income is g dollars, where 30,700≤g≤74,300. T(g)=4250+0.25(g−30,700) (a) What is the domain of the function T? The domain of the function T is {g| nothing≤g≤nothing}. (b) Given that the income tax due T is an increasing linear function of adjusted gross income g, find the range of the function T. The range of the function T is {T| ____≤T≤_____}. (c) Find adjusted gross income g as a function of income tax T. What are the domain and the range of this function? g(T)=_____ The domain of g(T) is {T| ___≤T≤_____}. The range of g(T) is {g| _____≤g≤_____}.arrow_forwardThis problem introduces a very reduced version of the inverse function theorem.arrow_forwardSuppose that y varies inversely as the 4th power of x, and that y=8y=8 when x=4x=4. What is y when x=8x=8? Round your answer to two decimal places if necessary.arrow_forward
