We don't know what's "not hard to understand" for you.
If you tell us what those words mean, we'll be glad to help you make a sentence using them.
Decay factor- the constant factor that each value in an exponential decay pattern is multiplied by to get the next value
Growth factor- a constant factor that each value in an exponential growth pattern is multiplied by to get the next value
Exponential form- a quantity expressed as a number raised to a power
Both the decay and growth factors are multiplied by exponential forms to get the next values.
why the hell didn't you give me the answer
Sure! Here's a sentence that includes the words "growth factor," "exponential form," and "decay factor": "When a quantity increases steadily over time, the growth factor can be represented in exponential form, while in cases of decreasing quantities, the decay factor is used."
