an exponential equation will look like
y = a(b)ˣ
now, the tale-tell guy is the "b" component, or growth/decay factor.
if "b" is less than 1, is decay, if "b" is greater than 1, is growth.
in this case b = 0.68, that's less than 1, so decay.
Answer:
y=2*0.68^x = exponential decay
Step-by-step explanation:
The time (t) it takes to clean an office building is <em><u>directly</u></em> <em><u>related</u></em> to the number of people (p) working.
t is proportional to p
