<h3>
<u>Explanation</u></h3>
where a-term determines the shape of graph.
h-term determines the change of graph for x-axis.
k-term determines the change of graph for y-axis.
Vertex of the graph is at (h,k).
- Substitute the vertex value in the equation.
We need to find the value of a-term. We have the given root which we can substitute in the equation.
<em>Also</em><em> </em><em>the</em><em> </em><em>roots</em><em> </em><em>are</em><em> </em><em>on</em><em> </em><em>x-axis</em><em>,</em><em> </em><em>meaning</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>y-value</em><em> </em><em>for</em><em> </em><em>roots</em><em> </em><em>must</em><em> </em><em>be</em><em> </em><em>0</em><em>.</em>
- Substitute (5,0) in the equation.
Therefore the value of a is - 1/2. Rewrite the equation as we get the answer.
