How to Graph a Parabola of the Form Y = a(x-h)^2 + k Step 1: Identify h and k from the equation, being careful to pay attention to the sign (positive or negative) on each number. The point (h,k) is the vertex of the parabola. For example, y=3(x+6)2−7 can be...
Press the "Graph" key to generate the curve on your TI-84 calculator's screen. Step 4 Press the "Window" key to access the window size menu and adjust the viewing window as necessary. For example, the parabola 3x^2 + 2x + 7 is best viewed in a window in which Xmin = 0, Xmax ...

Figure 4 shows the graph of the quadratic function written in general form as y=x2+4x+3.y=x2+4x+3. In this form, a=1, b=4,a=1, b=4, and c=3.c=3. Because a>0,a>0, the parabola opens upward. The axis of symmetry is x=−42(1)=...
The second equation graphs a straight line; the fourth equation is the familiar slope-intercept form; the last equation graphs a parabola. How to graph a circle equation A circle can be thought of as a graphed line that curves in both its x and y values. This may sound obvious, but con...
The graph of this equation is a parabola: Graph of a Parabola The equation of this graph: {eq}f(x)=x^2+x-2 {/eq}, but it still satisfies the standard form. This equation has two solutions or points where it crosses the x-axis. Finding the method to get the square can give ...
Use the equation of a parabola (a U shaped graph) for the first equation. For this example, use the parabola equation y=x^2. Type the right side of the equation, x^2, into the first function(equation) text box on your calculator. ...
Inside the absolute-value bars of this function, I've got a quadratic. Without the absolute-value bars, the graph of the quadratic inside the bars is a generic parabola.I can confirm (by factoring) that the x-intercepts are at x = −1 and x = 4. I can use a formula to confirm...
A parabola is a graph of a quadratic equation that has the shape of a U or an upside down U. There are several different forms of the equation of a parabola, and one such form is vertex form. This form of a parabola is y = a(x - h)2 + k, where a is a constant, and (h...
