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

[Riwaj]

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?
