How to graph a parabola with x x values?

Use the properties of the parabola to analyze and graph the parabola. Select a few x x values, and plug them into the equation to find the corresponding y y values. The x x values should be selected around the vertex. Tap for more steps… Replace the variable x x with − 1 – 1 in the expression.

How do I use function Grapher?

Function Grapher is a full featured Graphing Utility that supports graphing up to 5 functions together. You can also save your work as a URL (website link). To plot a function just type it into the function box. Use “x” as the variable like this: To zoom, use the zoom slider. To the left zooms in, to the right zooms out.

What is the Y-Y value at x = -2x = – 2?

The y y value at x = − 2 x = – 2 is 8 8. Replace the variable x x with 1 1 in the expression. Simplify the result. Tap for more steps…

How do you zoom in and out on a graph?

Use “x” as the variable like this: To zoom, use the zoom slider. To the left zooms in, to the right zooms out. When you let go of the slider it goes back to the middle so you can zoom more. You can click-and-drag to move the graph around.

What is the equation for Y = m2+bx+c?

THE PARABOLA y = m2+ bx + c You knew this function long before calculus. The graph crosses the x axis when y = 0. The quadratic formula solves y = 3×2-4x + 1 = 0, and so does factoring into (x -1)(3x-1). The crossing points x = 1 and x =f come from algebra. The other important point is found by calculus.

How do you find the vertex form of a parabola?

Consider the vertex form of a parabola. Substitute the values of a a and b b into the formula d = b 2 a d = b 2 a. Cancel the common factor of 0 0 and 2 2. Tap for more steps…

What is the Y-Y value at x = 2x = 2?

The final answer is 3 3. The y y value at x = 2 x = 2 is 3 3. Graph the parabola using its properties and the selected points. Graph the parabola using its properties and the selected points.
