How to find the vertex? I know the formula to find the vertex is x=-b/2a This is the question I have: Use complete sentences to explain how you would use graphing technology to find the solutions of 0 = 2x2 − 3x + 0.5. What do the solutions of 0 = 2x2 − 3x + 0.5 represent on the graph of the equation? By graphing technology they just mean geogebra or another graphing site. When I turned in my answer, my teacher said: If you are using a graphing technology, you just have to enter the equation into the technology and it graphs it. Then you should be able to identify the x intercept and the vertex. But when I plugged it in, I only got 2 different x-intercepts. I'm not sure what Im doing wrong.
There are only two x intercepts.
I forgot to mention I think I'm trying to graph a parabola.
Don't forget to report the vertex as well.
you should get a parabola, It looks like an arc and could cross the x-axis twice
I have the two x-intercepts, but I'm missing something for the parabola. Shouldn't it have three answers? I'm missing the minimum/maximum, but I'm not sure how to find it.
