Day 1: Introduction to Quadratic Functions

Front

Quadratic equations take the shape of a _______ when graphed.

Back

parabola

Front

Does this parabola have a minimum or maximum and what is its value?

Back

maximum: 5

Front

What is the vertex of a parabola?

Back

(0, 18)

Front

Does this graph have a maximum or minimum point?

Back

maximum

Front

What is the equation for the axis of symmetry?

Back

x=3

Front

Define a quadratic function.

Back

A quadratic function is a polynomial function of degree 2, typically in the form f(x) = ax² + bx + c.

Front

What is the standard form of a quadratic equation?

Back

The standard form is y = ax² + bx + c.

Front

What does the 'a' value in a quadratic function determine?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the highest or lowest point of the parabola, depending on whether it opens upwards or downwards.

Front

How do you find the axis of symmetry for a quadratic function?

Back

The axis of symmetry can be found using the formula x = -b/(2a).
