X=2 or y=-1
these are the points that the graph avoids
i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.
Then you would get 4x²-4x-8.
You then cannot simplify further. so your answer would be 4x²-4x-8.
The correct answer is 1/6
6. C. 748h = 1,500, because 34 x 22 = 748 x height 'h'
7. B. 59 + x, because sum means add
