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
[tex]\frac{x+4}{-5} = \frac{-5y}{-5}[/tex]
[tex]-\frac{x+4}{5} = y[/tex]
[tex]\frac{-x-4}{5} = y[/tex]
[tex]\frac{-1}{5}x - \frac{4}{5} = y[/tex]

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