Solve the problem.A triangular display of cereal boxes in a supermarket has 34 boxes in the bottom row, 31 boxes in the next row, and so on, in an arithmetic sequence. Find the general term for the sequence and how many rows there are in the display.
A. an = 37 - 3n; 12 rows in the display
B. an = 37 - 3n; 13 rows in the display
C. an = 34 - 3n; 11 rows in the display
D. an = 34 - 3n; 10 rows in the display

Provide an appropriate response.Determine all of the critical points of f(x, y) = 
x3 + x2 - 3x + 
y3 - 4y. Also use the second derivative test to determine, if possible, whether a maximum, minimum or saddle point occurs at each of these critical points.
What will be an ideal response?
State whether the parabola opens upward or downward.y = 5 - (x + 3)2
A. Upward B. Downward
Approximate the coordinates of each turning point by graphing f(x) in the standard viewing rectangle. Round to the nearest hundredth, if necessary.f(x) = -7x2 + 11x - 5
