Does the graph open up or down? How do you know? Explain whether the graph has a maximum or minimum point. Find the vertex and x-intercepts and y-intercepts of the graph

Answer 1

Does the graph open up or down? How do you know? Explain whether the graph has a maximum or minimum point. Find the vertex and x-intercepts and y-intercepts\[c^2-6c+9=0\] of the graph.

Answer 2

Given an equation f(x) = ax^2+bx+c. It opens up if a > 0.
To find the vertex, complete the square and write it in the vertex form
For the x-intercepts. Factor
For the y-intercepts. Set x=0

Answer 3

Or for the vertex use the fact that you have the x-intercepts. It's x-coord is half way between them
