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.
