The equation for exponential growth is typically expressed as ( N(t) = N_0 e^{rt} ), where ( N(t) ) is the quantity at time ( t ), ( N_0 ) is the initial quantity, ( r ) is the growth rate, and ( e ) is the base of the natural logarithm (approximately 2.71828). In this model, the quantity increases at a rate proportional to its current value, leading to a rapid increase over time.
No, the equation y = 102x is not exponential. An exponential function is of the form y = a * b^x, where a and b are constants. In this case, the equation y = 102x is a linear function, as it represents a straight line with a slope of 102 and no exponential growth or decay.
Any number below negative one.
It can be growth or decay - it depends on whether n is positive (growth) or negative (decay).

both have steep slopes both have exponents in their equation both can model population
If your equation is y=0.682x then yes

The r value in the exponential equation is the rate of natural increase expressed as a percentage (birth rate - death rate). So the math includes the birth rate and the death rate when implementing the equation. Students may have a hard time understanding that population growth is controlled not only by birth and death rates but also by the present population. The mathematics of exponential growth govern the prediction of population growth. Your welcome Ms. Musselma...'s class.

Exponential growth does not have an origin: it occurs in various situations in nature. For example if the rate of growth in something depends on how big it is, then you have exponential growth.

To determine if an equation represents exponential growth or decay, look at the base of the exponential function. If the base is greater than 1 (e.g., (y = a \cdot b^x) with (b > 1)), the function represents exponential growth. Conversely, if the base is between 0 and 1 (e.g., (y = a \cdot b^x) with (0 < b < 1)), the function indicates exponential decay. Additionally, the sign of the exponent can also provide insight into the behavior of the function.
Differential equations are essential for modeling exponential growth, as they describe how a quantity changes over time. Specifically, the equation ( \frac{dN}{dt} = rN ) represents the rate of growth of a population ( N ) at a constant growth rate ( r ). Solving this equation yields the exponential growth function ( N(t) = N_0 e^{rt} ), illustrating how populations or quantities increase exponentially over time based on their initial value and growth rate. This mathematical framework is widely applied in fields like biology, finance, and physics to predict growth patterns.
