Trigonometry homework question answer, step 1, image 1

 

here the initial point is (0,-4)

which means the function starts from the middle line

so our function is a sine function 

y=A\sin \left(bx\right)+c

here amplitude of the function is 3 so take A=3

y=3\sin \left(bx\right)+c

but after x=0, the graph is decreasing 

which means the graph reflected over the x-axis 

so we have to write -3 instead of 3

y=-3\sin \left(bx\right)+c
