Concept explainers
To prove: The conjecture of parabola and line.
Explanation of Solution
Given: The equation of parabola
The equation of parabola
First draw the graph of parabola and equation of line for different value of k .
Using graphing calculator graph shown below.
For
In graph,
Therefore, the solution of parabola and lines would be two solutions.
For
In graph,
Therefore, the solution of parabola and lines would be no solution.
For
In graph,
Therefore, the solution of parabola and lines would be one solution.
Hence proved
