Best ResponseYou've already chosen the best response.0for each function rewrite in vertex form same as set function = 0 and find the change in x value find the midpoint the axis of symmetry is the x value of the vertex put the these xvalues in order from lowest to highest number on the number line

Best ResponseYou've already chosen the best response.0i understand how to find f(x) and g(x) but i still dont understand how is x=b over 2a how can i find that with only 2x2
