Front

What is the axis of symmetry for the quadratic equation y=3x^2-6x+4?

Back

The axis of symmetry is x=1.

Front

How do you find the length of a missing side in a right triangle?

Back

Use the Pythagorean theorem: a^2 + b^2 = c^2, where c is the hypotenuse.

Front

Does the equation Y = -3x^2 + 7x - 2 open upwards or downwards?

Back

The equation opens downwards.

Front

What are the real roots of the quadratic equation y = 2x^2 + 4x + 5?

Back

There are no real roots.

Front

Solve for x in the equation 3y = 2g(x+h).

Back

x = \frac{3y}{2g} - h.

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax^2 + bx + c.

Front

What does the vertex of a parabola represent?

Back

The vertex is the highest or lowest point of the parabola.

Front

How do you determine if a quadratic opens upwards or downwards?

Back

If the coefficient of x^2 (a) is positive, it opens upwards; if negative, it opens downwards.

Front

What is the quadratic formula?

Back

The quadratic formula is x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}.

Front

What is the discriminant in a quadratic equation?

Back

The discriminant is b^2 - 4ac and determines the nature of the roots.
