What is the vertex of a parabola represented by the function $$y = ax^2 + bx + c$$ ?

The vertex can be found using the formula: $$x = -\frac{b}{2a}$$ .

How do you simplify the expression $$\sqrt{3^8}$$ ?

The expression simplifies to $$3^4$$ .

What is the quadratic formula used for?

The quadratic formula is used to find the roots of a quadratic equation: $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ .

What does it mean for two lines to be perpendicular?

Two lines are perpendicular if they intersect at a right angle (90 degrees).

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): $$c^2 = a^2 + b^2$$ .

How do you find the slope of a line given two points?

The slope (m) can be calculated using the formula: $$m = \frac{y_2 - y_1}{x_2 - x_1}$$ .

What is the definition of a function?

A function is a relation that assigns exactly one output for each input.

What is the difference between a rational and an irrational number?

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a simple fraction.

What is the formula for the volume of a cylinder?

The volume (V) of a cylinder is calculated using the formula: $$V = \pi r^2 h$$ , where r is the radius and h is the height.

What is the significance of the discriminant in a quadratic equation?

The discriminant (b^2 - 4ac) determines the nature of the roots: if positive, there are two real roots; if zero, one real root; if negative, no real roots.
