SUMMARY

The discussion focuses on calculating the intersection points of two graphs defined by the equations Y1 = (7x)/(x^2+1) and Y2 = (x^2+2x+5)/(x+2). To find the intersection points, one must set the two equations equal to each other and solve for the variable x. This method will yield the x-values where the graphs intersect, which can then be substituted back into either equation to find the corresponding y-values.

PREREQUISITES
  • Understanding of algebraic equations
  • Familiarity with functions and graphing
  • Knowledge of solving equations for a variable
  • Basic calculus concepts (optional for deeper analysis)
NEXT STEPS
  • Learn how to solve rational equations
  • Study methods for finding intersection points of functions
  • Explore graphing techniques for visualizing intersections
  • Investigate the use of graphing calculators or software like Desmos for verification
USEFUL FOR

Students, mathematicians, and anyone interested in graph theory or algebraic problem-solving will benefit from this discussion.

i have two graphs, i need to know how to calculate the points where the two graphs touch.

in my case there are two points.

do i have to make the equation equal or something?

the two equations are (7x)/(x^2+1)

and (x^2+2x+5)/(x+2)

Welcome to PF.

You mean that you have 2 equations Y(x).

And you want to identify where the values of Y are equal between the 2 equations.

Maybe if you set one = to the other and solved for x ...?
