What is a linear function?

Back

A linear function is a function that graphs to a straight line. It can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is an exponential function?

Back

An exponential function is a function of the form y = ab^x, where a is a constant, b is a positive real number, and x is the exponent. It grows or decays at a constant percentage rate.

Front

How can you identify a linear graph?

Back

A linear graph has a constant rate of change and forms a straight line when plotted on a coordinate plane.

Front

How can you identify an exponential graph?

Back

An exponential graph shows rapid growth or decay and curves upwards or downwards, rather than forming a straight line.

Front

What does the y-intercept represent in a function?

Back

The y-intercept is the value of y when x is 0. It represents the starting point of the function on the y-axis.

Front

What does the slope of a line indicate?

Back

The slope indicates the rate of change of the function. A positive slope means the function is increasing, while a negative slope means it is decreasing.

Front

What is the meaning of the term 'domain' in 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 meaning of the term 'range' in 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 is a function?

Back

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

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values increase, the output values also increase.
