Help me with equations
Mrrafil [7]
Hey there! 

Assuming that "f" =  y

So, let's solve your function,  shall we? 

y(-1) = 2 \\ \\ \\ -y= 2 \\ \\ DivideBy(-1)  \\ \\ \\   \frac{-y}{1}  =  \frac{2}{-1} \\ \\ \\ CancelOut:  \frac{-y}{1}  \\ \\ \\ Keep:  \frac{2}{-1}  \\ \\ \\ \\ Answer: y = -2 (option D)

Good luck on your assignment and enjoy your day!
