tour falls the following quadratic ce have the same access of symmetry. Well, we contest this In general, problems of this form is Lon zero and the access of cemetery is always given by the following equation Just negative. B over two A So we'Ll just make this computation for both graphs here. So for this one, we'LL have negative b over two A. So that will be negative five over four and then for other graph negative b over two times a day and then go ahead and simplify that So we can rewrite this as minus fifteen over twelve and we see that three does go into both of these, so that would be negative. Five over four. So in each case, when we write out the equation for access the cemetery, they're both the same equation. They're both X equals negative five over four. So the answer here is Yes, this is true. And that's our final answer
