Which transformation from the graph of a function f(x) describes the graph of f(x)-1?

Answer:Step-by-step explanation:Any side to side movement of a function will be reflected inside a set of parenthesis with the x.  For example, if the function was a parabola, the parent graph could be, very simply,[tex]y=x^2[/tex]Side to side movement would make the equation look like this:[tex]y=(x-h)^2[/tex]where h is the x coordinate of the vertex.Up or down movment would make the equation look like this:[tex]y=x^2+k[/tex] for movement upwards, or[tex]y=x^2-k[/tex] for movement downwards.  The k represents the y coordiante of the vertex in this parabola.Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.
