The coordinate of the turning point is (1,4) and the coordinates of the roots are (-1,0) and (3,0)

How to determine the coordinate of the turning point?

This is the vertex of the equation.

The equation is the given as:

y = 3 + 2x - x^2

According to the graph, the vertex is at the coordinate (1,4)

Hence, the coordinate of the turning point is (1,4)

How to determine the coordinate of the roots?

The equation is the given as:

3 + 2x - x^2 = 0

According to the graph, the equation crosses the x-axis at (-1,0) and (3,0)

Hence, the coordinates of the roots are (-1,0) and (3,0)
