Correct option is

C

8

Given polynomial is p(x)=4x  

2

−3x+7  

We need to find value of polynomial at x=1.

Then put the value of x=1 in the given polynomial, we get

p(x)=4(1)  

2

−3(1)+7

⇒p(x)=4×1−3×1+7

⇒p(x)=4−3+7

⇒p(x)=11−3=8

So, value of polynomial is 8.

Answer 2

Answer:

12

Step-by-step explanation:

p(x) =4*2-3x+7

p(1) =4*2-3*1+7

=8-3+7

=5+7

=12
