Question

5) IF P(x) = x2-x+1 then find the value of P(-1) and P (1​

Answer 1

Answer:

if P(x)=x^2-x+1 is given and we have to find P(-1) and P(1)

Step-by-step explanation:

(i)P(-1)=?

substitute -1 in function P(x) with x

then P(-1)= (-1)^2-(-1)+1 = 1+1+1= 3

so P(-1)= 3

(ii)P(1)=?

substitute 1 in function P(x) with x

then P(1)= (1)^2-(1)+1 = 1-1+1= 1

so P(1)= 1
