Parabolas can have both xintercepts and y intercepts yintercept As you can see from the picture below, the yintercept is the point at which the parabola intercepts the yaxis xintercepts The xintercepts are the points or the point at which the parabola intersects the xaxis A parabola can have either 2,1 or zero real x interceptsUse the discriminant to state the number and type of solutions for the equation negative 3x squared plus 5x minus 4 is equal to 0 and so just as a reminder you're probably wondering what is the discriminant and we can just review it by looking at the quadratic formula so if I haven't found a quadratic equation in standard form ax squared plus BX plus C is equal to 0 we know that theIn this video, we graph the trinomial / quadratic function y = x^2 4x 12 by finding its concavity, yintercept, using the turning point formulas and the

The intercepts of a graph are points at which the graph crosses the axes The xintercept is the point at which the graph crosses the xaxisAt this point, the ycoordinate is zeroThe yintercept is the point at which the graph crosses the yaxisAt this point, the xcoordinate is zero To determine the xintercept, we set y equal to zero and solve for xSet the right side equal to zero Notice we have a quadratic equation in the form of where , , and Let's use the quadratic formula to solve for x Start with the quadratic formula
