Unit 3: Key Features of Functions Practice

Front

What is the maximum of a function?

Back

The maximum of a function is the highest point on the graph of the function. It represents the largest value of the function over its domain.

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. It is represented as (0, y) where y is the value of the function when x = 0.

Front

What is the x-intercept of a function?

Back

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

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 y-intercept from a function's equation?

Back

To find the y-intercept, set x = 0 in the function's equation and solve for y.

Front

How do you find the x-intercept from a function's equation?

Back

To find the x-intercept, set y = 0 in the function's equation and solve for x.

Front

What does it mean if a function has no maximum?

Back

If a function has no maximum, it means that the function continues to increase indefinitely and does not reach a highest point.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a quadratic function?

Back

A quadratic function is a function that can be expressed in the form y = ax^2 + bx + c, where a, b, and c are constants and a ≠ 0.
