Front

What is the formula for the area of a triangle?

Back

Area = 1/2 * base * height

Front

Define a polynomial function.

Back

A polynomial function is a function that can be expressed in the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_0 are constants and n is a non-negative integer.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, meaning they have the same slope.

Front

What is the Pythagorean theorem?

Back

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): a^2 + b^2 = c^2.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

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

Back

A rational number can be expressed as a fraction a/b where a and b are integers and b ≠ 0. An irrational number cannot be expressed as a simple fraction.

Front

What is the vertex form of a quadratic function?

Back

The vertex form of a quadratic function is f(x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Front

Define the term 'function'.

Back

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

Front

What is the quadratic formula?

Back

The quadratic formula is x = (-b ± √(b^2 - 4ac)) / (2a), used to find the roots of the quadratic equation ax^2 + bx + c = 0.

Front

What is the difference between a linear function and a quadratic function?

Back

A linear function has the form f(x) = mx + b and graphs as a straight line, while a quadratic function has the form f(x) = ax^2 + bx + c and graphs as a parabola.
