The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What does it mean for a function to be positive?

Back

A function is positive when its output values (y-values) are greater than zero.

Front

How do you identify the x-intercept of a function?

Back

The x-intercept is the point where the graph of the function crosses the x-axis, which occurs when y = 0.

Front

What is a parabola?

Back

A parabola is a U-shaped graph that represents a quadratic function, defined by the equation y = ax^2 + bx + c.

Front

What is the vertex of a parabola?

Back

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

Front

What is the difference between a minimum and maximum value of a function?

Back

A minimum value is the lowest point on the graph, while a maximum value is the highest point.

Front

How can you determine if a parabola opens upwards or downwards?

Back

If the coefficient of x^2 (a) is positive, the parabola opens upwards; if negative, it opens downwards.

Front

What is the significance of the y-intercept?

Back

The y-intercept is the point where the graph crosses the y-axis, occurring when x = 0.

Front

What does it mean for a function to be continuous?

Back

A function is continuous if there are no breaks, jumps, or holes in its graph.

Front

What is a function?

Back

A function is a relation that assigns exactly one output value for each input value.
