Alright, so if I understand you correctly, you have a quadratic and are asked to find the vertex and x-intercept. I'd begin by looking up your book's definition of those words. What is the vertex of a function? More specifically, what is the vertex of a quadratic, and how might you find it? Then, what is the x-intercept of a function? For this one, you might find it easier to graph the function. When you reply back, please show any work you've done on this problem (even if you know it's wrong) and where you're getting stuck, so we can provide better assistance. Thank you.
