Question

Find the axis of symmetry, vertex and y - intercept of the function

Answer 1

see explanation

Explanation:

The axis of symmetry is a vertical line with equation x = c

Where c is the x- coordinate of the turning point, that is

x = - 1

The coordinates of the vertex, the turning point are (- 1, - 6 )

The y- intercept is where the graph crosses the y- axis , that is

y- intercept = - 3
