Question

Write the Nature of graphical solution.

Answer 1

Graphical Solution

The graphical solution is the solution obtained from the intersecting point of the lines. The graphical solution of the equation can be determined by using the steps given below:

Step 1: Understand the ordered pair of numbers, abscissa and ordinate in graph.

Step 2: Form the coordinates of a point by appropriate substitution.

Step 3: Locate the coordinate points obtained from Step 2 of each given equation on the graph.

Step 4: Join the plotted points by lines.

Step 5: Observe the lines of intersection, which is the solution of the equations.

Answer 2

Hii

We can solve a quadratic equation by factoring, completing the square, using the quadratic formula or using the graphical method.

Compared to the other methods, the graphical method only gives an estimate to the solution(s). If the graph of the quadratic function crosses the x-axis at two points then we have two solutions. If the graph touches the x-axis at one point then we have one solution. If the graph does not intersect with the x-axis then the equation has no real solution.
