  1. If a linear function f satisfies f(4) = 5 and f(10) = 2, find f(x).

    $\displaystyle y={{5\,x}\over{4}}+{{21}\over{2}}$ $\displaystyle y={{5\,x}\over{4}}-{{21}\over{2}}$ $\displaystyle y=-{{x}\over{2}}-7$ $\displaystyle y=7-{{x}\over{2}}$

  2. Solve the equation $\displaystyle -2\,x^2-6\,x+4=0$.

    $\displaystyle \left[ x=3-\sqrt{5} , x=\sqrt{5}+3 \right] $ $\displaystyle \left[ x=-{{\sqrt{17}+3}\over{2}} , x={{\sqrt{17}-3}\over{2}} \right] $ [ x = −2 ,  x =  − 1 ] $\displaystyle \left[ x=-{{\sqrt{17}-3}\over{2}} , x={{\sqrt{17}+3}\over{2}} \right] $
