Linear vs Exponential

Front

What is a linear function?

Back

A linear function is a function that creates a straight line when graphed. It has the form y = mx + b, where m is the slope and b is the y-intercept.

What is an exponential function?

Back

An exponential function is a function where the variable is in the exponent. It has the form y = a * b^x, where a is a constant, b is the base, and x is the exponent.

How does a linear function grow?

Back

A linear function grows at a constant rate. For every unit increase in x, y increases by a fixed amount.

How does an exponential function grow?

Back

An exponential function grows at an increasing rate. As x increases, y increases by a larger amount each time.

What is the slope in a linear function?

Back

The slope (m) in a linear function represents the rate of change of y with respect to x.

What does the base represent in an exponential function?

Back

The base (b) in an exponential function determines the growth rate. If b > 1, the function grows; if 0 < b < 1, it decays.
