Short demo on graphing a parabola by finding the vertex and yintercept, and using the axis of symmetry Since the slope of the graph is positive (mainly positive 1/2), y is going to increase as you increase x If we start at x=0, then y = 2, and if we increase this at all, say move to x=8, y = 2, which is bigger than what we previously had which wa Equation y 2 = x represents a parabola with vertex at origin and its axis as x axis Equation x y = 2 represents a line passing through (2, 0) and (0, 2) On solving these two equations, we get point of intersections The points of intersection of line and parabola are (1, 1) and (4, –2) These are shown in the graph below
