<div>I have a question that asks to find the equation of the two lines so that I can find (fog)(0). One equation is shown on a graph and the other is shown in a table. It says for the table: for g(x): (0,-1),(-1,2),(2,4)</div>
<div>and the points shown on the graph are: (0,-1),(-1,2),(2,0). I think I have to use the formula f(x)= (x+(point crossing x axis))multiplied by(x-(other point crossing x axis)) and you get your answer but when I plugged in the information I got a weird answer that I don't think is right for the both of them. </div>Sun, 22 Feb 2015 14:35:51 -06002015-02-22T14:35:51-06:00321528https://www.wyzant.com/resources/answers/77425/graphing_parabolas_in_all_forms_e_g_y_4_x_4_2_3Amber from Cedar Knolls, NJhttps://www.wyzant.com/resources/answers/users/view/85486370ParabolasGraphing Graphing Parabolas in All forms e.g y=4 (x-4)^2 -3 <div>Please I really need math help, I have tried really hard to get this question but I always end up even more confused than I was went I tried the problem the first time. </div>Wed, 11 Feb 2015 01:51:46 -06002015-02-11T01:51:46-06:00332136https://www.wyzant.com/resources/answers/88355/y_16x_2_190x_0KT from Orlando, FLhttps://www.wyzant.com/resources/answers/users/view/85656786Parabolasy=16x^2+190x+0<div>my daughter has to graph a parabola however when inputting the equation, it appears to be almost a straight line and not the vertex as seen in examples. help.</div>
