Question

Seja f(x)=2x²-3x+1 calcule x se f(x)=1

Answer 1

Resposta:

2x² -3x + 1 = 1

2x² - 3x = 0

x(2x -3) = 0

x = 0

2x -3 = 0

respostas:

x = 0

x = 3/2

Answer 2

Resposta:

quando f(x)=1:

$f(1) = 2 \times {1}^{2} - 3 \times 1 + 1$

$f(1) = 2 \times 1 - 3 + 1$

$f(1) = 2 - 3 + 1$

$f(1) = - 1 + 1$

$f(1) = 0$
