SUMMARY

The discussion focuses on the function g(x) = (kx - p)/2, where g(7) = 8 and g(5) = 5. Participants conclude that the values of k and p can be derived from the given g(x) outputs. The problem emphasizes the need to find k and p rather than x, as x is already defined by the inputs 5 and 7. Additionally, the concept of an onto function is introduced, specifically regarding the function f(x) = x + 1.

PREREQUISITES
  • Understanding of linear functions and their representations
  • Knowledge of function outputs and how to solve for variables
  • Familiarity with the concept of onto functions in mathematics
  • Basic algebraic manipulation skills
NEXT STEPS
  • Calculate the values of k and p using the equations derived from g(7) and g(5)
  • Research the definition and properties of onto functions in mathematics
  • Explore examples of linear functions and their graphical representations
  • Study the implications of function mappings in set theory
USEFUL FOR

Students and educators in mathematics, particularly those focusing on algebra and function theory, as well as anyone seeking to understand the properties of linear functions and onto functions.

1) If g(x) = \frac{kx-p}{2} , g(7) = 8 , g(5) = 5 then find the value of x and g(x) .
2 )Show that f : N \implies N and f(x) = x+1 is onto function .

We ask that our users show their progress (work thus far or thoughts on how to begin) when posting questions. This way our helpers can see where you are stuck or may be going astray and will be able to post the best help possible without potentially making a suggestion which you have already tried, which would waste your time and that of the helper.

Can you post what you have done so far?

? x has values 5 and 7 and the corresponding values of g(x) are 5 and 8. You are GIVEN that! A more reasonable problem would be to find the values of k and p.

2 )Show that f : N \implies N and f(x) = x+1 is onto function .

Do you know what "onto function" means? What is the definition?
