    If x measures time (in years) then the value of y this year is 0.35·2.3^x, and next year it's 0.35·2.3^(x+1) so, can u calculate annual increase from this ?

    u just subtract 0.35·2.3^x from 0.35·2.3^(x+1)

    is that a x sign in between 0.35 and the 2.3^x ?

    and i believe the Question is \(y=0.35 (0.23)^x\) right ? and yes.

    \(\% increase=(final-initial)*100/initial \) here, initial is =0.35·2.3^x final =0.35·2.3^(x+1)

    130% is correct in this instance. Consider the percent increase from 0.35(2.3)^1 to 0.35(2.3)^2

    For growth functions, the easiest way to determine the growth rate is to consider it of the form: y = a(1 + r)^x, where r is the percent increase
