Semester Review Day 3

Front

What is the equation of a line in point-slope form?

Back

Front

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

Back

To find the x-intercept of a line, set y = 0 in the equation of the line and solve for x.

Front

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

Back

To find the y-intercept of a line, set x = 0 in the equation of the line and solve for y.

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 from a graph, identify the lowest and highest points on the y-axis that the graph reaches.

Front

What does the notation -3 ≤ y < 2 mean?

Back

The notation -3 ≤ y < 2 means that y can take any value from -3 to 2, including -3 but not including 2.

Front

What is the difference between a closed interval and an open interval?

Back

A closed interval includes its endpoints (e.g., [a, b]), while an open interval does not include its endpoints (e.g., (a, b)).

Front

How do you write the range of a function in interval notation?

Back

The range of a function in interval notation is written using brackets for closed intervals and parentheses for open intervals, e.g., [a, b) or (a, b].

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).

Front

How do you find the slope from two points?
