Use a table to graph the quadratic function (written in vertex form): \( f(x)=3(x+1)^{2}-1 \)

(2) Calcula las siguientes potencias. \( \begin{array}{llll}\text { a) }\left(\frac{4}{3}\right)^{-1} & \text { b) }\left(-\frac{2}{4}\right)^{-4} & \text { c) }\left(-\frac{4}{7}\right)^{-1} & \text { d) }\left(\frac{10}{7}\right)^{2}\end{array} \)

Construct a \( \triangle P Q R \) in which \( Q R=5 \mathrm{~cm}, \angle Q=25^{\circ} \) and \( \angle R=55^{\circ} \).

1. Se realiza un experimento biológico al virus sars \( \operatorname{cov} 2 \), la reproducción de este está dada por: \( y=\frac{4}{2+8 e^{-2 x}} \)

Question 1 (continued) (d) Make \( t \) the subject of the equation: \( 5 t-3 a t=a-a t \)

The coordinate notation shows how the coordinates of a figure are relat to the coordinates of its image after transformations. What are the transformations? Are the figure and its image congruent? Explain. \( \begin{array}{ll}\text { 8. }(x, y) \longrightarrow(4 x-1,4 y+2) & \text { 9. }(x, y) \longrightarrow\left(\frac{1}{2} x,-\frac{1}{2} y\right)\end{array} \)
