Front

What does the equation y = mx + b represent?

Back

It represents a linear function where m is the slope (rate of change) and b is the y-intercept (initial value).

Front

What is the definition of slope (m) in the context of a linear equation?

Back

Slope (m) is the rate of change, calculated as rise over run (change in y over change in x).

Front

What does b represent in the equation y = mx + b?

Back

b represents the initial value or the y-intercept of the linear function.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

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

What do open and closed circles represent on a number line?

Back

Open circle indicates less than or greater than; closed circle indicates less than or equal to or greater than or equal to.

Front

What is the difference between independent and dependent variables?

Back

Independent variable (x) is the input, while the dependent variable (y) is the output that depends on the input.

Front

What is the domain of the exponential function y = a^x?

Back

The domain of the exponential function y = a^x is all real numbers.

Front

What does the term 'rate of change' refer to in mathematics?

Back

Rate of change refers to how much a quantity changes in relation to another quantity, often represented by the slope in linear functions.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x = 0.
