1. Use the vertical line test to decide whether graphs \( A, B \), or both represent functions. Which of the graphs is a function? B Both Neither

49. \( \frac{6}{\sqrt{2}} \) kasrinin maxracini irrasionalliqdan azad

Value: 2 The graph of the quadratic function given by the equation \( f(x)=-\frac{1}{2}(x-1)^{2} \) will fip upside down because there is a negative sign in front. True False

El numero \( \frac{1}{\sqrt[3]{2}} \) puede expresarse en forma de potencia de exponente negativo como \( 2^{-\frac{1}{3}} \) Expresar de la misma forma. \( \frac{1}{\sqrt[3]{5}} ; \frac{1}{\sqrt[5]{2}} ; \frac{1}{\sqrt[4]{5}} ; \frac{2}{\sqrt[3]{9}} ; \frac{-2}{\sqrt[6]{3}} \)

3. Resolver las siguientes operaciones con raíces. \( \frac{\sqrt{3^{3}} \cdot \sqrt[4]{5^{5}}}{\sqrt{3} \cdot \sqrt[5]{2^{3}} \cdot \sqrt[5]{2^{2}} \cdot \sqrt[4]{5}} \)

3) If \( f(x)=\frac{1}{x} \) for \( x>0 \), then \( f(1.5)= \) \( \begin{array}{llll}\text { (A) } \frac{3}{4} & \text { (B) } \frac{2}{3} & \text { (C) } \frac{1}{2} & \text { (D) } \frac{1}{3} \\ \text { (E) } \frac{1}{4}\end{array} \)
