Question

Find the value of the polynomial 2x-2x³ +7 using given values for x

■x=3

■x=-1

■x=0​

Answer 1

Step-by-step explanation:

Given polynomial = –2x³ + 2x + 7

• For x = 3

⇒ p(3) = –2(3)³ + 2(3) + 7

⇒ p(3) = –2(27) + 6 + 7

⇒ p(3) = –54 + 13

⇒ p(3) = –41

Value of the polynomial when x = 3 is –41

• For x = –1

⇒ p(–1) = –2(–1)³ + 2(–1) + 7

⇒ p(–1) = –2(–1) – 2 + 7

⇒ p(–1) = 2 + 5

⇒ p(–1) = 7

Value of the polynomial when x = –1 is 7

• For x = 0

⇒ p(0) = –2(0)³ + 2(0) + 7

⇒ p(0) = –2(0) + 7

⇒ p(0) = 7

Value of the polynomial when x = 0 is 7

Answer 2

Answer:

p (0) = 7

2x - 2x ³ + 7
