\ \textgreater \ means you shade the part above the line, and \ \textless \ means you shade the part under the line.

If it has an equal bar under it, like this: \leq  or \geq, then you also shade the line, by making it solid instead of dotting it.

Identify one characteristic of exponential growth
Sonbull [250]

Answer:

Range is always greater than zero.

Step-by-step explanation:

An exponential growth means that the growth rate of a given quantity increases exponentially.

The graph of an exponential function is shown below.

From the above graph, it's quite clear that the range of the function is never negative.

Hence, one characteristic of exponential growth is that the range(y values on the graph) is always greater than zero.
