48. Mouse Population A certain breed of mouse was intro- duced onto a small island with an initial population of 320 mice, and scientists estimate that the mouse population is dou- bling every year. (a) Find a function that models the number of mice after ? (b) Estimate the mouse population after 8 years.

Between 2000 and 2020, the population of Mathville could be modeled by the function \( m(t)=100 \sqrt[3]{t} \), where \( m(t) \) is the number of people in Mathville and \( t \) is the number of years since 2000. Between those same years, the population of Calcfield could be modeled by the function \( c(t)=18 t \). Graph the functions. At what point do the functions intersect?

Hallen las ecuaciones paramétricas para la trayectoria de una partícula que se mueve sobre la circunferencia \( x^{2}+(y-1)^{2}=4 \), en cada uno de los siguientes casos: a) Comenzando en \( (2,1) \), recorriendo la circunferencia una vez en el sentido horario.

b) Dada la sucesión \( f_{1}=-2, \quad f_{2}=1 \quad f_{k}=3 f_{k-1}-f_{k-2}, k \geq 3 \). Encuentre \( f_{t}, \quad f_{j+2}, \quad f_{k-3} \) y \( \quad f_{h+1} \)

Verifica che il grafico di \( y=\frac{1}{1-x} \) ha un asin- toto verticale di equazio- ne \( x=1 \)

Sketch the graph of each function. \( y=\frac{1}{4} \cdot\left(\frac{1}{3}\right)^{x-1}-1 \)

Begin by graphing \( f(x)=3^{x} \). Then use transformations of this graph to graph the given function. Be sure to graph and give the equation of the asymptote. Use the graph to determine the function's domain and range. If applicable, use a graphing utility to confirm your hand-drawn graphs. \[ h(x)=3^{x+2}-2 \] A. The graph of \( f(x)=3^{x} \) should be horizontally shifted 2 units to the left and vertically shifted 2 units upward. B. The graph of \( f(x)=3^{x} \) should be horizontally shifted 2 units to the left and correct answer below. vertically shifted 2 units downward. C. The graph of \( f(x)=3^{x} \) should be horizontally shifted 2 units to the right and vertically shifted 2 units downward. D. The graph of \( f(x)=3^{x} \) should be horizontally shifted 2 units to the right and to graph the function \( h(x)=3^{x+2}-2 \) ? Choose the vertically shifted 2 units upward.
