I1- Semester 1 Midterm review

Front

What is the range of a graph?

Back

The range of a graph is the set of all possible output values (y-values) that the function can produce. For example, if the graph only produces values greater than or equal to 0, the range is y ≥ 0.

Front

What does a zero slope indicate about a graph?

Back

A zero slope indicates that the graph is horizontal, meaning there is no change in the y-value as the x-value changes.

Front

What is a geometric sequence?

Back

A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.

Front

How do you find the common ratio in a geometric sequence?

Back

To find the common ratio, divide any term by the previous term. For example, in the sequence 500, 200, 80, 32, the common ratio is 200/500 = 2/5.

Front

What is the solution to the equation -11 + 3(b + 5) = 7?

Back

The solution is b = 1.

Front

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. For example, if x must be greater than 0, the domain is x > 0.

Front

What does it mean if a graph has an undefined slope?

Back

An undefined slope means the graph is vertical, indicating that there is no change in the x-value as the y-value changes.

Front

What is a positive slope?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, resulting in an upward slant of the graph.

Front

What is the formula for finding the slope of a line?

Back

The slope (m) of a line can be calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What is the difference between the domain and range of a function?

Back

The domain refers to the set of all possible input values (x-values), while the range refers to the set of all possible output values (y-values) of the function.
