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

    $\displaystyle y={{3\,x}\over{5}}-{{2}\over{5}}$ $\displaystyle y={{3\,x}\over{5}}+{{2}\over{5}}$ y = x + 2 y = x − 2

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

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