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 and 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.
