Question

Where does y = x² - x - 2 cross the y axis?

O (0,-2)
O (-1,0)
O (2,0)
O (1,-2)

Answer 1

(0,-2)

Explanation:

To find where the equation y = x² - x - 2 crosses the y-axis, you need to find the point where x is equal to 0 because the y-axis is where x = 0.

Substitute x = 0 into the equation:

y = 0² - 0 - 2

y = -2

So, when x = 0, y = -2. Therefore, the y = x² - x - 2 crosses the y-axis at the point (0, -2), corresponding to option O (0, -2).
