$y'' = 12\theta + 14$ $y'''= 12$
First, we can distribute the $\theta^2$ to simplify the problem: $y = 2\theta^3 + 7\theta^2$ To find the second derivative, you need to find the first derivative first, so we differentiate the equation using the power rule: $y' = 6\theta^2 + 14\theta$ Then we find the derivative of $y'$ to find $y''$ using the power rule: $y'' = 12\theta + 14$ Finally, to find $y'''$, we find the derivative of $y''$ as follows: $y'''= 12$
