First we write the equation of the Parabola in standard form:
f%28x%29=a%28x-h%29%5E2%2Bk+,where (h, k) is the vertex of the Parabola.
In our case we have: f%28x%29=%28x%2B2%29%5E2%2B0, and the vertex is (-2, 0).
The value of x that produces the minimum is x=-2 and the value of the minimum is f(-2)=0. See the graph below:
