If a 0 does the graph open up or down
WebThe graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the ...

To do that, follow these steps: Rearrange the terms in descending order. This step gives you – x2 + 10 x = MAX. Factor out the leading term. You now have –1 ( x2 – 10 x) = MAX. Complete the square. This step expands the equation to –1 ( x2 – 10 x + 25) = MAX – 25.
