Determine in which direction the parabola opens y equals x2-7x plus 18?

y=x^2-7x+18

when x is large negative, or large positive, y is large, so it opens upward.

Opens Upward.

The graph opens upward.

To determine the direction in which the parabola opens, you need to look at the coefficient of the x^2 term in the equation. In this case, the equation is y = x^2 - 7x + 18.

The coefficient of the x^2 term is 1, which is positive.

When the coefficient of the x^2 term is positive, the parabola opens upwards.

So, the parabola in the equation y = x^2 - 7x + 18 opens upwards.
