The inverse of the function
, making option B,
, the correct choice.
To find the inverse of the function
, you switch the roles of x and y and then solve for y.
1. Replace f(x) with y:
![\[y = (1)/(4)x + 10\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/zy9vytyu91z1evrgwfs1jvbl7fzoe5h9t6.png)
2. Swap x and y:
![\[x = (1)/(4)y + 10\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/u7lwvnp630norba9qf6zsiaiymfav1dw24.png)
3. Solve for y:
![\[4x = y + 40\] \[y = 4x - 40\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/oizdwqzvwfgzp2214wla2mat7x6cf17nlc.png)
Therefore, the inverse function is:
![\[f^(-1)(x) = 4x - 40\]](https://img.qammunity.org/2024/formulas/mathematics/high-school/9hp9ex6ovu3agdqete9lopecd7j5vk8phz.png)
So, the correct answer is:
B.
