here the x and y intercepts are actually the same point the origin we will need at least one more point so that we can graph the line graphing lines using intercepts how to find the x intercepts of a quadratic equation jennarocca calculating the y intercept labce com laboratory how to find the x intercept of a quadratic equation jennarocca sketching a parabola if the x intercepts exist ppt how to find the x intercept of a quadratic equation jennarocca creategraph2qq example 2 given equation vertex y coordinate axis of symmetry solution to find the x intercept set y 0 finding intercepts given the graph for any parabola we will find the vertex and y intercept in addition if the x intercepts exist then we will want to determine those as well definition of x and y intercepts the graph of a quadratic function image titled find the y intercept step 12 using the fact that a parabola is symmetric we can determine the vertical line of symmetry using the x intercepts to do this we find the x value midway how to find the x y intercepts of rational functions math wonderhowto how to find abc curve direction y intercept quadratic eq math wonderhowto now let s look at the process of finding the x x and y y intercepts of a quadratic equation we ll use the equation y x 2 2x 3 y x 2 2 x image titled graph a quadratic equation step 9 finding the equation of a quadratic given zeros and another point the parabola of the flight of the toy and write this quadratic equation in vertex form standard form and factored form some find the x intercepts 8 example 3 finding a quadratic equation with the x intercepts and another point example b find the x and y intercepts example 2 try this on your own first sketching a quadratic function 10 x standard 14 graph and yze quadratic functions how to graph x y intercepts on a ti 84 plus calculator math wonderhowto 12 y intercept therefore the vertex is 3 0 which happens to be the same point as the x intercept so far we have only two points to determine three more graphing quadratic equations example graph the quadratic equation a find the y intercept b 4 find given y x 2 6x 3 find 2 2 y x 2 2x 8 6 complete the following how to identify the slope and y intercept given y mx b math wonderhowto we can see that the x value of the x intercept is a mixed number between 2 and 3 to algebraically find x intercepts recall that we must set y 0 and
