Aich of the following is an irrational number? B. \( \sqrt{67} \) C. 1.9 D. \( \sqrt{9} \) B

\( f(x)-2 \)

\( \begin{array}{lll}\text { a. }-1,-8 & \text { b. } 7,8 & \text { c. }-7,8 \\ \text { Find the value of the roots for the quadratic equation } x^{2}+11 x+24 \\ \begin{array}{lll}\text { a. } 8,-3 & \text { b. }-8,3 & \text { c. } 8,3\end{array}\end{array} \)

Suppose that \( \ln 3= \) a and \( \ln 11=b \). Use properties of logarithms to write the logarithm in terms of a and \( b \). \( \ln \sqrt[3]{33} \) \( \ln \sqrt[3]{33}=\square \)

Vertical and horizontal and reflections and compressions change the change the shape of the graph.
