Algebra EOC Vocabulary

What is the range of a quadratic function that opens upwards?

• All y-values greater than or equal to the y-coordinate of the vertex.

• All y-values less than or equal to the y-coordinate of the vertex.

• All y-values greater than the y-coordinate of the vertex.

• All y-values between the vertex and the x-axis.

What are all possible y-values of a function called?

• Domain

• Range

• Set of Inputs

• Function Values

What is the term for the set of all possible x-values of a function?

• Range

• Domain

• Limit

• Function

What does it mean for a function to be absolute value?

• The output is always non-negative, creating a V-shaped graph.

• The output can be negative, resulting in a linear graph.

• The output is always zero, leading to a flat line.

• The output varies randomly without any specific pattern.

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

• Linear functions have a degree of 1, while quadratic functions have a degree of 2.

• Linear functions are represented by a straight line, while quadratic functions are represented by a curve.

• Linear functions can have a degree of 2, while quadratic functions can have a degree of 1.

• Linear functions have a constant rate of change, while quadratic functions do not.

What is the standard form of a quadratic function?

• y = ax^2 + bx + c

• y = a(x - h)^2 + k

• y = mx + b

• y = ax^3 + bx^2 + cx + d

What is the vertex of a parabola?

• The point where the parabola intersects the x-axis.

• The highest or lowest point on the graph of a quadratic function.

• The point where the parabola intersects the y-axis.

• The axis of symmetry of the parabola.

What does the function notation f(x) represent?

• x

• f

• y

• g

What are the zeros/solutions/roots of a function asking for?

• Y values

• X values

• Z values

• Function values

In the vertex (x, y), who is the axis of symmetry?
