How do you find the inverse f-1(x) given f(x)=x^3+7?
Anuta_ua [19.1K]

Answer:

f^{-1}(x)=\sqrt[3]{x-7}

Step-by-step explanation:

First let me list the steps to find the inverse of a function.

1) Replace f(x) with y

2) Swap the locations of x's and y's

3) Solve for y

4) Replace y with  f^{-1}(x)

Now lets do this with this function

f(x)=x^3+7\\\\y=x^3+7\\\\x=y^3+7\\\\y^3=x-7\\\\y=\sqrt[3]{x-7}\\\\f^{-1}(x)=\sqrt[3]{x-7}

If it's 10
nasty-shy [4]
There are 6 time zones in the US: Hawaiian, Alaskan, Pacific, Mountain, Central, and Eastern. To figure out the time in different zones start with what you know: It's 10 am in the Eastern zone, and LA is in Pacific time. Now go back to the list and count backwards from Eastern to Pacific: 3. For each different time zone subtract 1 from 10: 10-3=7. In LA it would be C. 7 am :)
