Problem

State whether the parabola defined by the quadratic function below opens up or down. \[ f(x)=3 x^{2}-2 x+2 \] Up Down

Solution

Step 1 :The direction in which a parabola opens is determined by the sign of the coefficient of the \(x^{2}\) term in the quadratic function. If the coefficient is positive, the parabola opens upwards. If the coefficient is negative, the parabola opens downwards.

Step 2 :In this case, the coefficient of the \(x^{2}\) term is 3, which is positive.

Step 3 :Therefore, the parabola opens upwards.

Step 4 :Final Answer: The parabola defined by the quadratic function \(f(x)=3 x^{2}-2 x+2\) opens \(\boxed{Up}\).
