Question

Help me with equations

Answer 1

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!
