Find dy/dx and day/dx2. x = t2 + 3, y = t2 + 3t dy = dx = dx2 For which values of t is the curve concave upward? (Enter your answer using interval notation.)Find the points on the curve where the tangent is horizontal or vertical. if you have a graphing device, graph the curve to check your work. (Enter your answers as a comma-separated list of ordered pairs.) X=[33t, y=t26 horizontal tangent (X. Y) = |:| vertical tangent (x, y) = Use a graph to estimate the coordinates of the rightmost point on the curve x = 5t 7t5, y = er. Then use calculus to find the exact coordinates. M=(E) Find the surface area generated by rotating the given curve about the y-axis. x = 9t2, y = 6+3, outs1 327.5525 X
