An exponential function can have negative y-values.
However, a real-world exponential decay model will never have negative values. Think of it this way... If you divide a positive number by 2 (or take half of it) and then divide that next number by 2, you will never reach or go below 0.
For Example:
20, 10, 5, 2.5, 1.25, 0.625, 0.3125, etc.
(Each number is half of the number before it.)
It can be growth or decay - it depends on whether n is positive (growth) or negative (decay).
An exponential model is one in which the dependent variable, y, is related to the independent variable, x by a function of the formy = a*b^x or, equivalently, y = a*e^cx where a, b ad c are constants of the model and e is Euler's number, which is also the base of natural logarithms.

One example of an exponential relationship is the growth of bacteria in a controlled environment, where the population doubles at regular intervals. In contrast, a linear relationship can be observed in the distance traveled by a car moving at a constant speed over time. In both cases, the exponential model captures rapid growth, while the linear model illustrates steady, uniform change.

both have steep slopes both have exponents in their equation both can model population
Into nothing at all? No, but it can decay from one thing into another completely. Using the exponential function to model out decay is an accurate estimate for large quantities of a substance, but if there are only a few hundred particles or so of something, the process is discrete and not continuous, so the exponential model is inaccurate.
Reverend Thomas Malthus developed the concept of Exponential Growth (another name for this is Malthusian growth model.) However the mathematical Exponent function was already know, but not applied to population growth and growth constraints. Exponential Decay is a natural extension of Exponential Growth
Yes, the model of decay accurately represents the exponential decrease in the number of radioactive nuclei over time. This model is supported by experimental data and mathematical calculations. It is commonly used to predict the remaining amount of a radioactive substance at any given time.
the answer must be exponential growth model.

In a scatter plot that is an exponential model, data can appear to be growing in incremental rates. In this type of model the data will only cross the Y-axis at one point.

The validity of the projection depends on the validity of the model. If the model is valid over the domain in question then the projection is valid within that domain. If the model is not then the projection is not. And that applies to all kinds of graphs - not just exponential.
The exponential model of population growth describes the idea that population growth expands rapidly rather than in a linear fashion, such as human reproduction. Cellular reproduction fits the exponential model of population growth.
An exponential model has a j-shaped growth rate that increases dramatically over a period of time with unlimited resources. A logistic model of population growth has a s-shaped curve with limited resources leading to a slow growth rate.
