STAAR Exit Review : Linear, Quadratic & Exponential

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

What does it mean if a function's range is y > 0?

Back

It means that the function only produces positive output values.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the graph of a parabola, depending on its orientation.

Front

How do you find the vertex of a quadratic function in standard form?

Back

For a quadratic function in the form f(x) = ax^2 + bx + c, the vertex can be found using the formula x = -b/(2a).

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis, represented as (0, f(0)).

Front

In the function f(x) = 13(0.27)^x, what does 13 represent?

Back

13 is the initial value or y-intercept of the function.

Front

What is an x-intercept?

Back

The x-intercept is the point where the graph of the function crosses the x-axis, represented as (x, 0).

Front

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

Back

To find the x-intercept, set the function equal to zero and solve for x.

Front

What variable represents the domain of a function?

Back

The domain of a function is represented by the variable x.

Front

What is the domain of a function?

Back

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