Question

Which function is the inverse of f(x)=4x-5

Answer 1

Answer:

f−1(x)=x/4+5/4

Step-by-step explanation:

interchange the variables and solve for y

Answer 2

Answer:

$f^{-1}$(x)=$\frac{x+5}{4}$

Step-by-step explanation:

To find the inverse, you must switch x and y.

y=4x-5 becomes x=4y-5

Solve the equation, first by adding 5 over

x=4y-5

x+5=4y

Divide by 4 on both sides

$\frac{x+5}{4}$=y
