NC Math 4 Review for Final Part 1

Front

What is the y-intercept?

Back

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

Front

What does it mean if a graph has a minimum?

Back

A graph has a minimum if it reaches a lowest point in its range. This means that the function value is lower than all other values in a certain interval.

Front

What is the y-intercept of the function represented by the point (0,7)?

Back

The y-intercept is (0,7), meaning the function crosses the y-axis at y = 7.

Front

How do you translate a function left and up?

Back

To translate a function left by 4 units and up by 7 units, you adjust the function's equation to include (x + 4) and add 7 to the output.

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

What is the difference between a maximum and a minimum in a graph?

Back

A maximum is the highest point in a graph, while a minimum is the lowest point. They indicate the peak and trough of the function's values.

Front

How do you identify the y-intercept from an equation?

Back

To find the y-intercept from an equation, set x = 0 and solve for y.

Front

What does the notation (-∞, 5] represent?

Back

The notation (-∞, 5] represents the domain of a function that includes all real numbers less than or equal to 5.

Front

What is a function?

Back

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