Explanation:
Remember that, this is quadratic function graph.
Let's analyze fact the graph. We get :
- There are two roots/zeroes
- Two roots are x1 = -2 , x2 = 6
- Vertex is maximum value of parabola (2,14)
- Symmetry function is x = 2 (you can show that, x-axis from vertex)
- "a" parabola indicated negative
- The parabola with "a" negative, thus have maximum value (show that vertex is (2,14))
Conclusion :
The true statements are C,F,I,K,N,O (6 statements are shown)
