HI!!

misty1212 · Answer

is the base bigger than one or less than one? that is how you know if it is growth or decay

naveenbhatia1312 · Answer

so its growth

misty1212 · Answer

ok and what is the number $1.02$ as a percent?

misty1212 · Answer

actually scratch that, probably just easier to ask what is the number $.02$ as a percent

naveenbhatia1312 · Answer

.0102

misty1212 · Answer

lol no you moved the decimal the wrong direction!

naveenbhatia1312 · Answer

102

misty1212 · Answer

other way $$1.02=102\%$$ so $100\%+2\%$ means $2\%$ more

naveenbhatia1312 · Answer

@misty1212 would the answer be the first one?

Decide whether the function is an exponential growth or exponential decay function and find the constant percentage rate of growth or decay. 

f(x) = 2063 ⋅ 0.9953x
	Exponential decay function; -0.47%
	Exponential decay function; 0.0047%
	Exponential growth function; 0.0047%
	Exponential growth function; -0.47%

misty1212 · Answer

yes it would be the first one for the one we just did

misty1212 · Answer

here the base is less than one, so it is decay
to find the percent, compute $$1-.9953$$ and then turn your answer in to a percent

misty1212 · Answer

looks like it must be A here too

naveenbhatia1312 · Answer

Ok cool.
