$y = x^2 + 2x + 5$

$y = 2x^2 + 3x + 1$

$y = x^2 + 2x + 3$

Obavezno

1

Convert the quadratic equation from vertex form $y = (x - 2)^2 + 3$ to standard form.

$y = x^2 - 4x + 7$

$y = x^2 - 4x + 3$

$y = x^2 + 4x + 7$

$y = x^2 + 4x + 3$

Obavezno

1

Convert the quadratic equation from standard form $y = x^2 + 6x + 8$ to vertex form.

$y = (x + 3)^2 - 1$

$y = (x - 3)^2 + 1$

$y = (x + 3)^2 + 1$

$y = (x - 3)^2 - 1$
