  1. If a linear function f satisfies f(1) = 3 and f(7) = 0, find f(x).

    y = 3x − 21 $\displaystyle y=-{{x}\over{2}}-{{7}\over{2}}$ $\displaystyle y={{7}\over{2}}-{{x}\over{2}}$ y = 3x + 21

  2. Solve the equation $\displaystyle 2\,x^2+3\,x+1=0$.

    $\displaystyle \left[ x=1 , x={{1}\over{2}} \right] $ $\displaystyle \left[ x=-{{\sqrt{5}+3}\over{2}} , x={{\sqrt{5}-3}\over{2}} \right] $ $\displaystyle \left[ x=-{{\sqrt{17}+3}\over{4}} , x={{\sqrt{17}-3}\over{4}} \right] $ $\displaystyle \left[ x=-{{1}\over{2}} , x=-1 \right] $
