A curve C is defined by the parametric equations x = 0 - t, y = 8 + t. Determine where the curve is concave upward or downward. The correct answer is: concave down on (0,0), concave up on (-1,0), concave down on (~0, -1), concave up on (~x, -1).

Step 1
Instead, we need to look at the first derivatives. I' = 1 V' = 1 The slope of the curve is positive, which means it is increasing as t increases. Show more…
