     The figure shows the graph of a quadratic function y f(x). Use it to find the minimum value of f(x) The minimum value of f(x) is (Type an integer or a fraction.) y=f(x) (-10,10 141210-8-6-4 8 10121  
  
  Solution
the given graph is parabola
it is upward direction
so, the vertex is low point on the graph
vertex is (-10,10)
the minimum value is 10
