Question

f(x)=x²+2x sendo f(2)+f(3)-f(1)​

Answer 1

Olá,

$\rightarrow\blue{\boxed{ \red{ \boxed{20}}}}$

F(x) = x² + 2x

• F(2) = x² + 2x
• F(2) = 2² + 2 × 2
• F(2) = 4 + 2 × 2
• F(2) = 4 + 4
• F(2) = 8

• F(3) = x² + 2x
• F(3) = 3² + 2 × 3
• F(3) = 9 + 2 × 3
• F(3) = 9 + 6
• F(3) = 15

• F(1) = x² + 2x
• F(1) = 1² + 2 × 1
• F(1) = 1 + 2 × 1
• F(1) = 1 + 2
• F(1) = 3

• F(2) + F(3) - F(1) =
• 8 + 15 - 3 =
• 23 - 3 =
• 20
