Draw the graph. The domain is [0, oo) (why?). It's an increasing function. The tangent is a vertical line at (0, -2) (why?) with equation x = 0. There's no point on the graph at which the tangent is horizontal (why?).
Hint: The derivative is $\displaystyle \left( \frac{3}{4} \right) 4 x^{-1/4} = 3 x^{-1/4} = \frac{3}{x^{1/4}}$.
