To find the minimum value of the parabola
, we can complete the square to equation in vertex form.Step 1: Start with the given equation:
Step 2: Complete the square by adding and subtracting
inside the parentheses:
Step 3: The vertex form of a parabola is
, where
is the vertex of the parabola. In this case, the vertex is
.Step 4: Since the coefficient of
is positive, the parabola opens upwards. Therefore, the vertex represents the minimum point of the parabola.Step 5: The minimum value of the parabola is the y-coordinate of the vertex, which is
.Therefore, the minimum value of the parabola
is
.
