Determine in which direction the parabola below opens. y = x² - 7x + 18
Left, right, up, down

Solution:

The standard form of a parabola is y = ax² + bx + c

Where a ≠ 0

1. Parabola opens up if a > 0 and has a maximum turning point

2. Parabola opens down if a < 0 and has a minimum turning point

In the given equation

y = x² - 7x + 18

a = 1 > 0 so the parabola opens up

Therefore, the parabola opens up.

Determine in which direction the parabola below opens. y = x² - 7x + 18

Summary:

The parabola y = x² - 7x + 18 opens up.
