Answer 4 :

→ Option b), 1

Explanation :

The highest power of the variable in a polynomial is called as the degree of the polynomial.

Answer 5 :

→ Option c), 2

Explanation :

The highest power of the variable in a polynomial is called as the degree of the polynomial.

Answer 6 :

→ Option a), 1

Explanation :

The highest power of the variable in a polynomial is called as the degree of the polynomial. The degree of a non-zero constant polynomial is zero.

Answer 7 :

→ Option a), 3

Explanation :

p(0) = 5x - 4x² + 3

→ 5(0) - 4(0)² + 3

→ 0 - 0 + 3

→ 3

Answer 8 :

→ Option b), -6

Explanation :

p(-1) = 5x - 4x² + 3

→ 5(-1) - 4(-1)² + 3

→ -5 -4(1) + 3

→ - 5 - 4 + 3

→ -9 + 3

→ - 6

Answer 9 :

Option b), 0

Explanation :

→ x(x + 1) -1(x + 1)

→ x² + x - x - 1

→ x² - 1

p(1) = x² - 1

→ (1)² - 1

→ 1 - 1

→ 0

Answer 10 :

Option b), 2

Explanation :

p(0) = -t³ + 2t² + 0 + 2

→ -(0)³ + 2(-0)² + 0 + 2

→ -0 + 0 + 0 + 2

→ 2

Answer 11 :

Option a), 4

Explanation :

p(2) = -t³ + 2t² + t + 2

→ - (2)³ + 2(2)² + 2 + 2

→ - 8 + 2(4) + 2 + 2

→ -8 + 8 + 2 + 2

→ 4

Answer 12 :

Option d), 1

Explanation :

y(0) = y² - y + 1

→ (0)² - 0 + 1

→ 0 - 0 + 1

→ 1

Answer 6 :

$\implies$Option a), 1

$\rule{190}1$

Answer 7 :

$\implies$Option a), 3

Explanation :

p(0) = 5x - 4x² + 3

$\implies$5(0) - 4(0)² + 3

$\implies$0 - 0 + 3

$\implies$3

$\rule{190}1$

Answer 8 :

$\implies$Option b), -6

Explanation :

p(-1) = 5x - 4x² + 3

$\implies$5(-1) - 4(-1)² + 3

$\implies$-5 -4(1) + 3

$\implies$- 5 - 4 + 3

$\implies$ -9 + 3

$\implies$- 6

$\rule{190}1$

Answer 9 :

Option b), 0

Explanation :

$\implies$x(x + 1) -1(x + 1)

$\implies$ x² + x - x - 1

$\implies$ x² - 1

p(1) = x² - 1

$\implies$(1)² - 1

$\implies$1 - 1

$\implies$0

$\rule{190}1$

Answer 10 :

Option b), 2

Explanation :

p(0) = -t³ + 2t² + 0 + 2

$\implies$-(0)³ + 2(-0)² + 0 + 2

$\implies$ -0 + 0 + 0 + 2

$\implies$2

$\rule{190}1$

Answer 11 :

Option a), 4

Explanation :

p(2) = -t³ + 2t² + t + 2

$\implies$ - (2)³ + 2(2)² + 2 + 2

$\implies$- 8 + 2(4) + 2 + 2

$\implies$-8 + 8 + 2 + 2

$\implies$ 4

$\rule{190}1$

Answer 12 :

Option d), 1

Explanation :

y(0) = y² - y + 1

$\implies$(0)² - 0 + 1

$\implies$0 - 0 + 1

$\implies$1
