Under a scale change, the image of the point (2, 4) is the point (1, -4). Find the equation of the image function, if the parent function is f(x) = x2
f(x) = -(x+1)2
f(x) = -(2x)2
f(x) = (-1/2 x)2
f(x) = -(1/2 x)2

If the graph of the parent function f(x) = x is shifted 7 units up and is horizontally compressed by a factor of 3, what is the function?
g(x) = f(7x) + 3
g(x) = 3f(x) - 7
g(x) = f(3x) + 7
g(x) = 7x - 3
