The product is the first one
[-4(-2)-8]+[-1-(-2)^3]+2(-2)^3
(8-8)+(-1+8)-64
7-64
57
The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.
The angles are congruent and corresponding. You can find the missing angles by subtracting the existing ones from 180.
