1. If a linear function f satisfies f(4) = 1 and f(11) = 6, find f(x).

    $\displaystyle y={{x}\over{4}}-{{13}\over{4}}$ $\displaystyle y={{x}\over{4}}+{{13}\over{4}}$ $\displaystyle y={{5\,x}\over{7}}+{{13}\over{7}}$ $\displaystyle y={{5\,x}\over{7}}-{{13}\over{7}}$

  2. Solve the equation $\displaystyle 3\,x^2-6\,x-3=0$.

    $\displaystyle \left[ x=1-\sqrt{2} , x=\sqrt{2}+1 \right] $ $\displaystyle \left[ x=3-2\,\sqrt{3} , x=2\,\sqrt{3}+3 \right] $ $\displaystyle \left[ x=-\sqrt{2}-1 , x=\sqrt{2}-1 \right] $ [ x = 1 ]
