    Answer:

                 a. the  vertex represents a minimum point

                 b.  f(x) = (x + 5)² – 5

    Step-by-step explanation:

    a.

    a = 1 > 0  ← that means the parabola opens up, so the vertex is minimum of the function

    b.

      f(x)=x^2+10x+20\\\\f(x)=\underline{x^2+10x+25} - 25+20\\\\f(x)=(x+5)^2-5
