Cuestionario 1. Dadas las funciones, utilizar la definición de derivada, \( y \) calcularla en cada uno de los puntos: a) \( f(x)=2 x+1 \), cuando \( x=3 \) b) \( g(x)=3 x^{2}+2 x \), cuando \( x=-1 \)

1. I can apply quadratic models in word problems. e.g. A piece of wire measuring 80 cm in length is bent into the shape of a rec be the width of the rectangle. i Use the perimeter to find an expression for the length of the rectangle in ii Hence, find a rule for the area of the rectangle, \( A \mathrm{~cm}^{2} \), in terms of \( x \) and for suitable values of \( x \). iii Use the graph to determine the maximum area that can be formed and the of the rectangle that give this area.

Halla los cinco primeros términos de la sucesiōn con \( a_{n}=\left(\frac{n-1}{n}\right)^{2} \) Comprueba \( a_{n}=\frac{1}{n} \) es el término general de la sucesiōn \( 1, \frac{1}{2}, \frac{1}{3}, \frac{1}{4} \ldots \)

Mr Muthu had a piece of rope that was 410 cm long. He cut 9 identical pieces from it and had 5 cm left over How long was each piece of the rope that he cut?

What is the gradient of the straight line \( 3 x+5 y=20 \). \( \begin{array}{ll}\text { A } 3 & \text { C }-\frac{3}{5}\end{array} \)
