# Find derivatives of the functions defined as follows. y=3\dot{}4^{x^{2}+2}

Composite functions
$$\displaystyle{y}={3}\dot{{\lbrace}}{4}^{{{x}^{{{2}}}+{2}}}$$
$$\displaystyle{\frac{{{\left.{d}{y}\right.}}}{{{\left.{d}{t}\right.}}}}={\left({6}{x}{\ln{{4}}}\right)}\dot{{\lbrace}}{4}^{{{x}^{{{2}}}+{2}}}$$
