  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
