variables:
(1) p(x) = 4x2 - 3x + 7 at x = 1​

Answer 1

Answer:

hope it helps mark me as the brainliest

Step-by-step explanation:

ANSWER

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:

= -2

Step-by-step explanation:

4×2-3x+7 at x=1

3x=3×1

=3

4×2-3+7=?

= 8-3+7

= 8-10

= -2 Answer
