$\frac{d y}{d x} = 2 \cdot 2 x^{2 - 1} - 4 x^{1 - 1} + 0 \cdot 9^{0 - 1} = 4 x - 4$ $dy/dx = 2 * 2x^(2-1) - 4x^(1-1)+ 0 * 9^(0-1) = 4x - 4$

$\frac{d^{2} y}{{d x}^{2}} = 1 \cdot 4 x^{1 - 1} - 0 \cdot 4^{0 - 1} = 4$ $(d^2y)/dx^2 = 1 * 4x^(1-1) - 0 * 4^(0-1) = 4$

Explanation:

At first, differentiate the equation of $y$ $y$ and then differentiate the first differentiated equation to find the value of the second derivative.
