A graphing calculator is a great help for problems of this nature.
x ∈ {-5.63, -0.55, 2.59}
x ∈ {-5.63, -0.55, 2.59}
Answer:
Step-by-step explanation:
y = x² - 10x + 27
y = ax² + bx + c
This is the general form of the equation for a parabola.
We must convert it to the vertex form
y = (x - h)² + k, where (h,k) are the coordinates of the vertex.
We can do this by completing the square.
The figure below shows that your parabola has its vertex at (5,2).
