Question

Q.6 and 7 pls tell right ans

Answer 1

Q6) Option D

Q7) P(1) = 9

Step-by-step explanation:

Q6) options D isn't a Polynomial because The variable in the polynomial {√(2x)} isn't an integral power. All the variables should have an integral power to be a polynomial and should also follow other rules.

Note - {√(2x)} means (2x)^(1/2). as 1/2 isn't an integer, Option D isn't a Polynomial.

Q7) Putting the Value in equation [p(x)] to find out P(1).

$p(1) = 5( {1}^{2} ) - 3(1) + 7 \\ = (5 \times 1 ) - (3 \times 1) + 7 \\ = (5 - 3) + 7 \\ = 2 + 7 \\ = 9$

P(1) = 9

I hope it Helps!

Answer 2

Answer:

6. 6x+4 7. (b) 9

Step-by-step explanation:

6. because it has only 2 term

7. p(1)= 5(1×1)-3(1)+7

p(1)= 5-3+7

p(1)= 2+7

p(1)= 9
