Answer 1

see explanation

Explanation:

(a)

The turning point is where the curve reaches its lowest point before increasing again.

The coordinates of the turning point are (- 2, - 1 )

(b)

The roots are the points on the x- axis where the graph crosses.

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

Answer 2

a) (-2,-1) b) (-3,0) & (-1,0)

Explanation:

For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).

For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
