Consider the parametric curve: x t= Y = At which t value(s) is the tangent to this curve vertical? (Note: If there is more than one write them as a comma separated list) t = 0 Write the point(s) at which the tangent is vertical.(Note: If there is more than one write them as a comma separated list, e.g. (1,2).(3,4)) Use a graphing device to graph the curve and check your work. 49 - t t - 25t At which t value(s) is the tangent to this curve horizontal? (Note: If there is more than one write them as a comma separated list). 3 Write the point(s) at which the tangent is horizontal. (Note: If there is more than one write them as a comma separated list, e.g. (1,2).(3,4))
