An energy transformation flow diagram is shown. x is a type of energy and y is the location where the energy transformation is taking place. what do x and y represent? select one: a. x = chemical energy, y = wind turbine b. x = gravitational energy, y = wind turbine c. x = chemical energy, y = thermal power plant d. x = gravitational energy, y = thermal power plant

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
