Question

f(x) = 2(x - 3)^2 + 5

Answer 1

Explicação passo-a-passo:

$f(x) = 2(x - 3)^2 + 5 \\ \\ f(x) = 2((x - 3)(x - 3)) + 5 \\ \\ f(x) = 2( {x}^{2} - 6x + 9) + 5 \\ \\ f(x) = 2{x}^{2} - 12x + 18+ 5 \\ \\ \boxed{ \boxed{ \underbrace{ f(x) = 2{x}^{2} - 12x + 23}}}$

Answer 2

Resposta:

f(x)=2((x-3)*(x-3))+5

f(x)=2(x^2-6x+9)+5

f(x)=(2x^2-12x+18)+5

f(x)=2x^2-12x+23
