Question

3. if(x) = x2 - 5x + 1 then evaluate f(2)=f(-1)+F (1/3)​

Answer 1

Answer: -113/9

Step-by-step explanation:

• f(2)=2^2-5*(2)+1
• So, f(2)= -5

• f(-1)= (-1)^2- 5*(-1) +1
• So, f(-1)=7

• f(1/3)= (1/3)^2- 5*(1/3) +1
• So, f(1/3)= -5/9

Ans:

• => f(2)-f(-1)+f(1/3)
• => - 5 - 7 - 5/9
• => -113/9
