What is a y-intercept?

Back

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

Front

How do you find the y-intercept from a graph?

Back

To find the y-intercept, look for the point where the graph intersects the y-axis.

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 determine the range from a graph?

Back

To determine the range, identify the lowest and highest points on the graph and note the corresponding y-values.

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

How do you find the domain from a graph?

Back

To find the domain, look for the x-values that the graph covers, from the leftmost to the rightmost point.

What does the notation -3 ≤ x ≤ 3 mean?

Back

This notation indicates that x can take any value from -3 to 3, inclusive.

Front

What does the notation -2 ≤ y ≤ 10 mean?

Back

This notation indicates that y can take any value from -2 to 10, inclusive.

Front

If a graph has a y-intercept of (0, 4), what does this mean?

Back

It means that when x = 0, the value of the function (y) is 4.

Front

What is the significance of the x-axis in a graph?

Back

The x-axis represents the input values (x-values) of a function.
