There are two intersecting parabolas. The first parabola has x-intercepts at X = 3 and X = 5 and passing through the point (2,-1). The second parabola has x-intercepts at X = 1 and X = 4 and, y-intercept at y = 2. Determine the EXACT x-coordinates of the points of intersection of the two parabolas. Sketch both parabolas on a graph clearly showing x-intercepts, vertex and points of intersection. (Use substitution method and quadratic formula)
