in this problem with were given that the Graf passes through the points minus three zero minus one for and also one zero. And also from the graph we see that this is the vertex. So since I have the Vertex we'LL call the standard form of a problem in general for tenses the point h Kama k So on our case, this becomes X minus negative one plus four Sorry for the square up there. Now we just need to find the value of a and so we're given some information regarding the ex intercepts. So let me use this fact over here this is f a born equal zero. So f one, I could also find it by just plugging in one and for X here. So we get for a plus four. However, by the given information, we know that this is also equal tau zero. So solve this for a this equation. Now here. And now that you have your new a value, just plug your A and back into the original F to obtain the following. So have a negative outside the parentheses. X plus one square plus four. So this is our parabola and the standard form
