Question

Which equation will produce the graph shown?

Answer 1

D

Explanation:

Since this we have rose petal, the equation will be either

`r = a \sin(n \alpha )`

or

`r = a \cos( n\alpha )`

Since we have 3 petals, which is a odd number, n=3

so the answer must be either

`r = a \cos(3a)`

`r = a \sin(3 \alpha )`

Where a is some constant real number.

So D is the answer
