Question

Find all for both functions.Growth or decay?A = B = % increase or decreaserangel1. y= 3(3/2)x 2. Y = 2(2/3)x

Answer 1

the given expression is

y = 3(3/2)^x

put x = 1

y = 3(3/2)

y = 9/2

put x = 2

y = 3 (9/4)

y = 27/4

so the percentage growth is,

`=((27)/(4)-(9)/(2))/((9)/(2))*100`
`\begin{gathered} =((27-18)/(4))/((9)/(2))*100 \\ =((9)/(4))/((9)/(2))*100 \\ =(9*2)/(4*9)*100 \\ \\ =50\text{ \%} \end{gathered}`
