Questions were; 1.from the graphs, write down a)the equation of the line of symmetry b)the coordinates of the turning point c)state whether 'a' is positive or negative

Here are the answers for the graphs:

For Graph (a):

a) The equation of the line of symmetry is:

$$x = 1$$

b) The coordinates of the turning point are:

$$(1, -9)$$

c) State whether 'a' is positive or negative:
Since the parabola opens upwards, 'a' is positive.

For Graph (b):

a) The equation of the line of symmetry is:

$$x = -2$$

b) The coordinates of the turning point are:

$$(-2, 9)$$

c) State whether 'a' is positive or negative:
Since the parabola opens downwards, 'a' is negative.
