1. Answer:

   its 2x-1

   Step-by-step explanation:

   this is the first degree polynomial with p(1)=1 and

   to calculate this answer you need to take a common first degree polynomial i.e. p(x)= ax + c

   now, putting x= 1

   we get, p(1)= a+c which is according to question equal to 1, i.e. a + c = 1

   similarly, p(2) = 2a + c which is equal to 3

   so, 2a + c = 3

   we can write it as a + a + c = 3

   i.e. a + 1 = 3 { from p(1) }

   so, a= 2

   putting it in any equation we get, c= -1

   so the ans is, 2x-1
