Answer:
Step-by-step explanation:
We are given that
f(0)=-3,f(1)=2,f(3)=5 and f(4)=0
We have to find the polynomial
Substitute the value x=0 then ,we get
f(0)=d=-3
Substitute x=1 then we get
(equation I)
Substitute x=3 then we get
(Equation II)
Substitute x=4 then we get
(Equation III)
Equation I multiply by 3 then subtract from equation II
(Equation IV)
Equation II multiply by 4 and equation III multiply by 3 and subtract equation II from III
(Equation V)
Equation IV multiply by 2 and then subtract from equation V
Substitute the value of a in equation IV then we get
Substitute the value of b in equation I then we get
Substitute the values then we get
