Question

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

Answer 1

Answer: A

Step-by-step 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

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

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

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

$\frac{-1}{5}x - \frac{4}{5} = y$

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