Sagot :

Answer:

see explanation

Step-by-step explanation:

(a)

The vertex is the turning point on the graph , U

coordinates of vertex = (1, - 9 )

(b)

The axis of symmetry is a vertical line passing through the vertex with equation

x = c ( c is the x- coordinate of the vertex ) , then

equation of axis of symmetry is x = 1

(c)

The zeros/ x- intercepts are the points on the x- axis where the graph crosses it.

The zeros are x = - 2 and x = 4

(d)

The y- intercept is the point on the y- axis where the graph crosses it.

The y- intercept = - 8U

(e)

This graph has a minimum at the vertex.

The minimum value is the y- coordinate of the vertex

minimum value = - 9

(f)

The graph is decreasing , going down, to the left of the vertex and increasing , going up, to the right of the vertex.

Then the graph is opening up

U ← opening up

∩ ← opening down
