For which values of $x$ is the slope of the line tangent to the graph of $h(x) = \frac{1}{2}x^4 - \frac{14}{3}x^3 + 10x^2 - 9$ horizontal? If there are multiple values, enter them as a comma-separated list. Enter DNE if no such values exist. $x = $

Find all values of x (if any) where the tangent line to the graph of the given equation is horizontal. HINT: [The tangent line is horizontal when its slope is zero.] (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) y = −9x^2 − 8x

Find all the values of x where the tangent line is horizontal. f(x) = 2x^3 + 39x^2 + 216x + 9 (Simplify your answer. Use a comma to separate answers as needed.)
