Question

Two different questions.. please try to answer both if possible!!!

Answer 1

Answer: A

Explanation:

f(x) = -5x - 4 ⇒ y = -5x - 4 switch the x's and y's and solve for y

x = -5y - 4

+4 +4

x + 4 = -5y

`(x+4)/(-5) = (-5y)/(-5)`

`-(x+4)/(5) = y`

`(-x-4)/(5) = y`

`(-1)/(5)x - (4)/(5)  = y`

***********************************************************

The top line of the second question is cut off so cannot help you without knowing what the restriction is on v(x).
