icang [17]

No it was not correct because if there is 12 inches in one foot and you divid 150 by 12 you get 12.6. Then you would multiply 12.6 and .15 and you would get 20.40. So you were charged extra with out tax.

Which of the following options results in a graph that shows exponential growth. F(x) = 0.4(3)^x. F(x) = 3(0.5)^x. F(x) = 0.8(0.

Andre45 [30]

$f(x)=a^x\\\\if\ a \ \textgreater \ 1\ then\ a\ function\ is\ an\ exponential\ growth\ function$

$f(x)=0.4(3)^x\to a=3 > 1\ OK!\\f(x)=3(0.5)^x\to a=0.5 < 1 :(\\f(x)=0.8(0.9)^x\to a=0.9 < 1 :(\\f(x)=0.9(5)^{-x}=0.9\left(\dfrac{1}{5}\right)^x\to a=\dfrac{1}{5} < 1\ :($

Answer: $f(x)=0.4(3)^x$
