Question

p(x)=2x^3‐5x+4 give p(2) and p(0)​

Answer 1

Answer:

The polynomial is p(x)=5x−4 we substitute x=2 in the polynomial:

p(2)=(5×2)−4=10−4=6

Hence, p(2)=6.

Answer 2

Step-by-step explanation:

if p(x) = p(0)

→ p(x) = 2x³ - 5x + 4

→ p(0) = 2(0)³ - 5(0) + 4

• 2 × 0 - 0 + 4
• 0 - 0 + 4
• 0 + 4
• 4

→ p(0) = 4

if p(x) = 2

→ p(x) = 2x³ - 5x + 4

→ p(2) = 2(2)³ - 5(3) + 4

• 2 × 8 - 15 + 4
• 16 - 15 + 4
• 1 + 4
• 5

→ p(2) = 5
