Can you tell me what these look like on a parabola graph?
X= 3
X= -3
X= 2.5
X= -15
On a parabola graph, x = 3 represents a vertical line passing through the point x = 3. Similarly, x = -3 represents a vertical line passing through the point x = -3.
X = 2.5 represents a vertical line at x = 2.5, and X = -15 represents a vertical line at x = -15 on the graph of a parabola.
