So you need to use the distributive property. First, solve inside the parentheses. So, 8x times 4y is 32xy, then multiply that by 3 to get 96xy, now multiply 96xy by 2 to get your final answer of 192xy.
The answer is B.
Hope it helps!
Answer:y^1=3 ,y^2=9 if im wrong sorry im wrong but hope you get an a
Answer:
Graph attached.
Step-by-step explanation:
In the question the given parameters are as followed.

1). Amplitude a = 7
2). Period = 
3). Vertical shift = 1 means mid line of the graph will be y =1 and maximum of the graph is 8 and minimum is -6.
