Warmup (Review Key Features of Functions)

Front

What is the domain of a function?

Back

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

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you find the x-intercepts of a function?

Back

The x-intercepts are found by setting the function equal to zero and solving for x.

Front

How do you find the y-intercept of a function?

Back

The y-intercept is found by evaluating the function at x = 0.

Front

What does it mean for a function to be increasing on an interval?

Back

A function is increasing on an interval if, as x increases, the value of the function also increases.

Front

What does it mean for a function to be decreasing on an interval?

Back

A function is decreasing on an interval if, as x increases, the value of the function decreases.

Front

What is a minimum of a function?

Back

The minimum of a function is the lowest point on the graph of the function within a given interval.

Front

What is a maximum of a function?

Back

The maximum of a function is the highest point on the graph of the function within a given interval.

Front

What is the vertex of a parabola?

Back

The vertex of a parabola is the point where the parabola changes direction, which can be a minimum or maximum.

Front

What is the standard form of a quadratic function?
