At what point does the line normal to the graph of y = m 3 + 23:2 at (1, 0) intersect the parabola a second time? C] = C] ) Hint: The normal line is perpendicular to the tangent line. If two lines are perpendicular their slopes are negative reciprocals i.e. if the slope of the rst line is mthen the slope of the second line is 1/m
