What type of transformation is g(x) if f(x) is the parent function?
g(x) = -3 f(x)
1) Vertical reflection and a vertical dilation - vertical stretch - scale factor = 1/3
2) Horizontal reflection and a horizontal dilation - horizontal stretch - scale factor = 1/3
3) Horizontal reflection and a horizontal dilation - horizontal stretch - scale factor = 3
4) Vertical reflection and a vertical dilation - vertical stretch - scale factor = 3
