Find the inverse of the function.<br> f-^1(x)= (x – 5)^3 + 1

Cloud [144]

Answer:

Step-by-step explanation:

To find the inverse of function y=f(x), swap variables and then solve for the original variable.

$y=(x-5)^3+1\\ \\ x=(y-5)^3+1\\ \\ x-1=(y-5)^3\\ \\ \sqrt[3]{x-1}=y-5\\ \\ y=\sqrt[3]{x-1}+5\\ \\ f^{-1}(x)=\sqrt[3]{x-1}+5$

Determine whether each relationship is a function. State the domain and range of each relation.

atroni [7]

<h2>Hello!</h2>

The answer is:

The relation is a function

Domain: {-5,-3,1}

Range: {6,3}

It's a function since each input (domain) has only one value at the output (range). A function exists when there is only a single value for each input, if there is more than one output for each input, the relation is not a function.

Have a nice day!
