Given:
There are given the equation:
[tex]y=x^2-10x+21[/tex]
Explanation:
According to the question, to find the vertex and roots first we need to draw the graph:
So,
The graph is:
On the given graph,
The vertex is:
[tex](5,-4)[/tex]
And,
The roots is:
[tex]x=(7,0),(3,0)[/tex]
Final answer:
Hence, by using the graph, the value of roots are shown below:
[tex]x=7,3[/tex]
