## How do you graph exponential decay?

Any graph that looks like the above (big on the left and crawling along the x-axis on the right) displays exponential decay, rather than exponential growth. For a graph to display exponential decay, either the exponent is “negative” or else the base is between 0 and 1.

**What is exponential growth and decay in math?**

Exponential growth is a mathematical change that increases without limit based on an exponential function. Exponential decay is found in mathematical functions where the rate of change is decreasing and thus must reach a limit, which is the horizontal asymptote of an exponential function.

### How do you tell if a graph is exponential growth or decay?

It’s exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It’s exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

**What is exponential growth and decay?**

exponential growth or decay function is a function that grows or shrinks at a constant percent growth rate. The equation can be written in the form f(x) = a(1 + r)x or f(x) = abx where b = 1 + r. r is the percent growth or decay rate, written as a decimal, b is the growth factor or growth multiplier.

## How do you find the growth decay factor on a graph?

When given a percentage of growth or decay, determined the growth/decay factor by adding or subtracting the percent, as a decimal, from 1. The variable x represents the number of times the growth/decay factor is multiplied.

**How do you know if a graph is exponential growth or decay?**

### How do you graph exponential growth?

An exponential growth function can be written in the form y = abx where a > 0 and b > 1. The graph will curve upward, as shown in the example of f(x) = 2x below. Notice that as x approaches negative infinity, the numbers become increasingly small.
