  1. If a linear function f satisfies f(2) = 1 and f(9) = −1, find f(x).

    $\displaystyle y={{x}\over{2}}-{{11}\over{2}}$ $\displaystyle y={{11}\over{7}}-{{2\,x}\over{7}}$ $\displaystyle y=-{{2\,x}\over{7}}-{{11}\over{7}}$ $\displaystyle y={{x}\over{2}}+{{11}\over{2}}$

  2. Solve the equation $\displaystyle -2\,x^2+4\,x+2=0$.

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