The figure shows the graphs of the function y = f(x) and y = g(x). The four indicated points all have integer coordinates. If g(x) = k ∙ f(x), what is the value of k? On f(x), the two indicated points are (0,1) and (1,1)
On g(x), the two indicated points are (0,3) and (1,3) Think of what the ycoordinates on f(x) are multiplied by, in order to get the ycoordinates on g(x). On f(x), 1 is multiplied by 3 to get 3 on g(x). and On f(x) 1 is multiplied by 3 to get 3 on g(x). Therefore if g(x) = k ∙ f(x), then the value of k is 3. Ask Algebra House Comments are closed.
