Consider the parametric curve: = 16 - y = - 4t 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 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)) 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). t = 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)) Use a graphing device to graph the curve and check your work
