What is a linear equation?

Back

A linear equation is an equation of the first degree, meaning it has no exponents greater than one. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Quadratic function.

Front

What is the general form of a quadratic function?

Back

A quadratic function can be expressed in the form y = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.

Front

How do you identify a quadratic function from a graph?

Back

A quadratic function's graph is a parabola, which opens either upwards or downwards.

Front

What is the vertex of a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

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

Back

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