In summary, the conversation discusses finding the value of x and g(x) in the given equation, and also asks for a proof that f(x) = x+1 is an onto function. The latter requires the understanding of the definition of an onto function.

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?
 

Related to If g(x) =(kx-p)/(2) , g(7) = 8 , g(5) = 5 then find the value of x and g(x)

What is the equation for g(x)?

The equation for g(x) is (kx-p)/(2).

What are the given values for g(7) and g(5)?

The given values are g(7) = 8 and g(5) = 5.

How can the value of x be found using the given information?

To find the value of x, we can use the given equations and substitute in the values for g(7) and g(5). This will result in two equations with two unknowns (k and p), which can be solved using algebraic methods.

What is the value of x when g(x) is equal to 0?

To find the value of x when g(x) is equal to 0, we can set the equation (kx-p)/(2) equal to 0 and solve for x. This will give us the value of x that makes g(x) equal to 0.

What is the relationship between the value of x and the values of g(7) and g(5)?

The value of x will determine the values of g(7) and g(5) since they are dependent on the equation g(x). Changing the value of x will in turn change the values of g(7) and g(5).
