The perimeter is 7, because 7 x 7 equals 49
Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above
The graph of each exponential function 
passes through the point (0,1), because 
Thus, the only possible choice is C.
Check it:
The set C could be generated by exponential function
