Answer:
![f^{-1}(x)=\sqrt[3]{x-7}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx-7%7D)
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 
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}](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3%2B7%5C%5C%5C%5Cy%3Dx%5E3%2B7%5C%5C%5C%5Cx%3Dy%5E3%2B7%5C%5C%5C%5Cy%5E3%3Dx-7%5C%5C%5C%5Cy%3D%5Csqrt%5B3%5D%7Bx-7%7D%5C%5C%5C%5Cf%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7Bx-7%7D)
The following statement are true about the given function
Statements i,ii, and iv
Given Data
We have the following function to analyse
y = 3x
The following statement are true/false about the given function
- The function is a direct variation: this is true because an increase in the x value will increase the y value
- The function goes through the origin: for x = 0, y = 0
- The constant of variation is 1/3: this statement is false, the constant of the variation is 3
- y is 6, when x is 2: this statement is true, when we plug x = 3, the corresponding value for y is 6
