How do you convert a percentage to a decimal?

Back

To convert a percentage to a decimal, divide the percentage by 100. For example, 5.5% as a decimal is 0.055.

What is a compound inequality?

Back

A compound inequality consists of two or more inequalities joined by 'and' or 'or'. It represents a range of values that satisfy all the inequalities.

What does it mean for a function to be decreasing?

Back

A function is decreasing if, as the input (x) increases, the output (f(x)) decreases. This means the slope of the function is negative.

Front

What is the x-intercept of a function?

Back

The x-intercept of a function is the point where the graph of the function crosses the x-axis. It occurs when f(x) = 0.

What is the significance of the y-intercept in a linear function?

Back

The y-intercept is the point where the graph of the function crosses the y-axis. It represents the value of the function when x = 0.

Front

What does it mean for a function to be negative for certain values of x?

Back

A function is negative for certain values of x if the output (f(x)) is less than zero for those x-values.

What is the relationship between the slope and the direction of a line?

Back

If the slope is positive, the line rises from left to right. If the slope is negative, the line falls from left to right. A slope of zero indicates a horizontal line.
