I need help with this problem. So do I start out with plugging in random values for x? Such as -2, -1, 0, 1, 2 and so on. And what do they mean by the "Graph the following function in the window -10 < x < 10, -10 < y < 10?" Thank you.

Is a Quadratic function ever a line?
Like I said, the easiest way to sketch a graph is to find the $\displaystyle x$ and $\displaystyle y$ intercepts and the turning point. This gives you an idea of the shape of the graph.
And then yes, you can plot points to make your graph a bit more accurate.
I thought the shape was suppose to be a parabola. Dang this problem is giving me a hard time. Sorry I don't have a graphing calculator so I don't really know how to solve this. And my teacher makes us write out the answer and explain how we got it also.
