Answers:

  • B) Shifted down 6 units
  • C) Shifted left 4 units
  • E) Reflected over x-axis

==============================================

Explanation:

The negative out front of the function tells us that we're multiplying the y coordinates by -1. This moves any (x,y) point to (x,-y). For example, a point like (1,2) moves to (1,-2). This is an x-axis reflection.

The jump from x to x+4 means the xy axis has moved 4 units to the right. Any input is now 4 units larger. If we kept the curve fixed in place while the axis moved, this gives the illusion the curve moves 4 units to the left.

Lastly the -6 at the very end will subtract 6 off whatever the y value is. This visually shifts the graph down 6 units.
