As already discussed, a quadratic equation has no real solutions if D < 0. They must read information from the graph (such as the vertical intercept of the quadratic graph or the slope of the linear one), use that information to construct and solve an equation, then interpret their. Interpret functions that arise in applications in terms of the context. If the vertex is at some other point on the graph, then a translation or a transformation of the parabola has occurred. Students will also learn how to use the viewing window to adjust the appearance of the graph for easier problem solving. by Nikita Bhardwaj. Find the average of the two x-intercepts, and substitute that x-value in to find the y-value. Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.
