The population of Whoville was 15,000 in the year 1991 when Dr. Seuss passed away and has been decreasing at a rate of 2% each year since. Which function, f(t), could be used to model the population of Whoville t years since 1991?

• f(t) = 15,000(1.02)^t

• f(t) = 1.02(15,000)^t

• f(t) = 0.98(15,000)^t

• f(t) = 15,000(0.98)^t

Which equation represents the transformation of the parent function: $y=\left(\frac{1}{9}\right)^x$  reflected over the x-axis shifted right 1 and up 2? 

•  $y=\left(9\right)^{\left(x+1\right)}+2$  

•  $y=-\left(\frac{1}{9}\right)^{\left(x+1\right)}+2$  

•  $y=-\left(\frac{1}{9}\right)^{\left(x-1\right)}+2$  

•  $y=\left(9\right)^{\left(x-2\right)}-1$  

Given: $f\left(x\right)=e^{\left(x+2\right)}-2$  and $g\left(x\right)=-3\left(\frac{1}{8}\right)^x-5$ .
