Pre-A REVIEW 8.1-8.6

Front

What does it mean when a car is stopped on a graph?

Back

The graph shows a horizontal line, indicating that the car's speed is 0 at that interval.

Front

How can you tell if a car is increasing speed on a graph?

Back

The graph shows an upward slope, indicating that the speed is increasing over time.

Front

What does a downward slope on a speed graph indicate?

Back

It indicates that the speed is decreasing over time.

Front

What is the initial value in a graph?

Back

The initial value is the starting point of the graph, often represented on the y-axis when x=0.

Front

How do you find the rate of change in a graph?

Back

The rate of change is found by calculating the slope of the line, which is the change in y divided by the change in x.

Front

What does a non-linear graph indicate?

Back

A non-linear graph indicates that the rate of change is not constant; the slope varies at different points.

Front

What is a function in mathematics?

Back

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

Front

What does it mean for speed to be a function of time?

Back

It means that speed changes over time and can be represented as a graph with time on the x-axis and speed on the y-axis.

Front

What is the significance of the y-intercept in a graph?

Back

The y-intercept is the point where the graph crosses the y-axis, representing the initial value of the dependent variable.

Front

How can you identify the maximum speed on a graph?

Back

The maximum speed is identified at the highest point on the graph, where the slope changes from positive to negative.
