Question

What are the values of p(x) is equal to x²-2x-3,-1and 2?

Answer 1

Answer:

Given: P (x) = x 2 − 2x + 5

Forx=−1, P (−1) = (−1) 2−2 (−1) + 5 = 1 + 2 + 5 = 8

For x = 5, P (5) = (5) 2−2 (5) + 5 = 25 − 10 + 5 = 20

Hence P (−1) = 8 and P (5) =2 0

Answer 2

Step-by-step explanation:

P(x) = x²-2x-3,

now x = -1

➳(-1)² - 2 × (-1) -3

➳1 + 2 - 3

➳3 - 3

➳0

• The value of P(x) = -1 is (0) .

now x = 2

➳2²-2×(2)-3

➳4 - 4 -3

➳0 -3

➳-3

• The value of P(x) = 2 is -3
