Question

The graph of a quadratic function passing through the point (1,-4) has its turning point at (-2,5). Write down the equation of the line of symmetry of the graph.​

Answer 1

x = - 2

Explanation:

the line of symmetry passes through the turning point and is a vertical line with equation

x = c ( where c is the x- coordinate of the turning point )

the turning point is (- 2, 5 ) with x- coordinate - 2 , then

equation of the line of symmetry is x = - 2
