Answer:
should be 192
Step-by-step explanation:
Answer:
The factored form is (sin x +2)(sin x-1)
Step-by-step explanation:
We have been given the trigonometric function 
We can factor this by AC method. In AC method we multiply the term a and c and then write the middle term b in such a way that the sum/difference is equal to the product 'ac'
Using the method, we can write sinx as 2sinx -sinx

Now, we group the first two terms and the last two terms

Now, we take GCF from each group

Factor out (sinx+2)

Therefore, the factored form is (sin x +2)(sin x-1)
F(x)=-3(x)+4
Therefore this implies that we must put the -4 where we see an X on the equation
F(-4)=-3(-4)+4
=16
I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
