Find the value of the following polynomial for the given values of the variable.

Value #1: x = -3
Value #2: x = -2

-x^2 - 5x -6 ? I am asked to find the distance between the verticies of the graphs of f(x)=2(x+4)^2-3 and g(x)= -(x+1)^2-3. According to the form f(x)= a(x-h)^2+k the vertex is (h,k). So the vert
