    f(x) - 3 means we shift EVERYTHING down 3 units. The point (0,2) moves to (0,-1) |dw:1438822641218:dw|

    say we know (0,2) lies on f(x) which point lies on -2*f(x) ?

    if (0,2) lies on f(x) then (0,-4) lies on -2*f(x)

    what this does is it flips the graph over the x axis and it makes it vertically stretch out |dw:1438823048318:dw|
