Find the value of each of the following polynomial for the indicate value of variable :
(1) p(x) = 4x² – 3x + 7 at x=1
(ii) q(Y) = 2y3 – 4y + Root 11 at y=1
(iii)r(t) = 4t4 +3t3 - +t2+6 at t=p, teR
(iv) s(z) = Z3 – 1 at z = 1
(v) p (x) = 3x² + 5x - 7 at x = 1
(vi) q (z) = 5z3- 4z + Root2 at Z = 2​

Answer 1

Answer:

Step-by-step explanation:

Given, q(y)=2y  

2

−4y+  

11

​

 

We need to find value of polynomial at y=1

Put the value y=1 in the given polynomial, we get

q(y)=2(1)  

2

−4(1)+  

11

​

 

⇒q(y)=2−4+  

11

​

 

⇒q(y)=2−4+3.32

⇒q(y)=1.32

Therefore, q(y)=1.32
