5.1: Modeling Data with Quadratic Functions

Question 1

Quadratic Function

Answer 1

A function that can be written in the standard form f(x) = ax squared + bx + c. The domain is all real numbers.

Question 2

Standard Form of a Quadratic Function

Answer 2

f(x) = ax squared (quadratic term) + bx (linear term) + c (constant term).

Question 3

Parabola

Answer 3

The graph of a quadratic function.

Question 4

Axis of Symmetry

Answer 4

The line that divides a parabola into two parts that are mirror images.

Question 5

Vertex of a Parabola

Answer 5

The point at which the parabola intersects the axis of symmetry. The y-value of the vertex of the parabola represents the maximum or minimum value of the function.
