I need help with steps for the horizontal part

Section 9.2: Problem 4 Previous Problem Problem List Next Problem (1 point) Consider the parametric curve: = 36 - +2 y 13 - 9t 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)) (36,0) 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.
