Question

Given the function f(x) = The quantity of 5x minus 3, divided by 4, which of the below expressions is correct?

Answer 1

Answer:

B. f−1(x) = The quantity of 4x plus 3, divided by 5

Step-by-step explanation:

Given

$f(x) = \frac{5x-3}{4}$

We have to find the inverse of the function

$Let\\f(x) = y\\y=\frac{5x-3}{4}\\4y=5x-3\\4y+3=5x\\\frac{4y+3}{5} =y$

So, the inverse of f(x) is:

$\frac{4y+3}{5}$

Hence,

The correct answer is:

B. f−1(x) = The quantity of 4x plus 3, divided by 5 ..
