101 Questions for Semester 1 Final Practice

Front

What is the vertex form of a quadratic function?

Back

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

Front

What does it mean for a graph to be symmetric with respect to the x-axis?

Back

A graph is symmetric with respect to the x-axis if for every point (x, y) on the graph, the point (x, -y) is also on the graph.

Front

What does it mean for a graph to be symmetric with respect to the y-axis?

Back

A graph is symmetric with respect to the y-axis if for every point (x, y) on the graph, the point (-x, y) is also on the graph.

Front

What does it mean for a graph to be symmetric with respect to the origin?

Back

A graph is symmetric with respect to the origin if for every point (x, y) on the graph, the point (-x, -y) is also on the graph.

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input. A table is not a function if any input corresponds to more than one output.

Front

How do you find the value of a function at a specific point, such as f(0)?

Back

To find f(0), substitute 0 for x in the function's equation and simplify to get the output value.

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

How do you determine if a table represents a function?

Back

A table represents a function if each input (x-value) corresponds to exactly one output (y-value). If any x-value has multiple y-values, it is not a function.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

The vertex of a quadratic function is the highest or lowest point on the graph, depending on the direction of the parabola.
