Which of these figures has rotational symmetry?

Rotational symmetry means it looks the same when it is turned.

So looking at those figures, B may look like a good option but notice that the edges are not the same length - if you rotate it, the shape would not EXACTLY match on top of it's original.

Option C and D are out since they don't have any symmetrical properties. Any way you turn them would give you a different shape.

That leaves you with A: try and rotate this image 180 degrees, it should look the same.

Therefore, the figure with rotational symmetry is A

the correct answer is a

Step-by-step explanation:

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
