How do you identify an exponential function from a table of values?

Back

Look for a constant ratio between consecutive outputs (y-values) when the inputs (x-values) increase by the same amount. If the ratio is constant, the relationship is exponential.

What does the base of an exponential function represent?

Back

The base of an exponential function indicates the growth (if > 1) or decay (if < 1) rate of the function.

What is the significance of the y-intercept in an exponential function?

Back

The y-intercept represents the initial value of the function, which is the value of the function when x = 0.

What is the difference between exponential growth and exponential decay?

Back

Exponential growth occurs when the base is greater than 1, leading to increasing values. Exponential decay occurs when the base is between 0 and 1, leading to decreasing values.
