Well, if it was out of 50, it would be 76%.
So the answer might be 50 questions total, but maybe there was 49 questions total.
I would probably go with 50 questions total.
Ok! So, given a quadratic function<span>, </span>y<span> = ax</span>2<span> + bx + c, when "a" is positive, the </span>parabola <span>opens upward and the vertex is the minimum value. On the other hand, if "a" is negative, the graph opens downward and the vertex is the maximum value. Now, let's refer back to our original graph, </span>y<span> = </span><span>x2</span><span>, where "a" is 1.
Hope this helps.</span>
You just need to divide 13 and 2 and get 6.5.
