Question

express y=x2+2x+3 for x=-4,0,4

Answer 1

Answer:

11

3

27

Step-by-step explanation:

case 1

x=-4

$y = {x}^{2} + 2x + 3 \\ y = { - 4}^{2} + 2( - 4) + 3 \\ y = 11$

case 2

x=0

y=3

case 3

$y = {x}^{2} + 2x + 3 \\ y = {4}^{2} + 2(4) + 3 \\ y = 27$

Answer 2

Answer:

Mark as brainliest answer.

Step-by-step explanation:

→ y = x² + 2x + 3

→ x = -4

→ y = (-4)² + 2(-4) + 3

→ y = 16 - 8 + 3

→ y = 11

→ x = 0

→ y = (0)² + 2(0) + 3

→ y = 0 + 0 + 3

→ y = 3

→ x = 4

→ y = (4)² + 2(4) + 3

→ y = 16 + 8 + 3

→ y = 27
