find vertex, intercepts, axis of y = x^2 - 3x + 4; sketch

[bthst3]

For y = xsquared - 3x + 4, find the cordinates of the vertex, the x and y intercepts, and the axis of symmetry. Sketch and label the graph.

Re: algebra

For \(\displaystyle y=x^2 - 3x + 4\), find the cordinates of the vertex, the x and y intercepts, and the axis of symmetry. Sketch and label the graph.

Please show us your work/thoughts and exactly where you are stuck

The graph is simple to draw, so I'll assume you're good on that part, and that you've got a good idea (from the graph) where the vertex and intercepts are. :wink:

To find the vertex exactly, either complete the square, or else use the formula (if that was provided to you). For the intercepts, do the same thing you've always done: To find the x (or y) intercept, plug zero in for y (or x), and solve!

The axis is the vertical line "x = h" through the vertex (h, k), so that part is easy, too. If you're not sure of your steps or your final answers, please show all of your work and reasoning. Thank you!
