Let $f(x)=4x^{2}12x-5$

Using the definition of derivative, $f^{\text{'}}(x)=\underset{h0}{lim}\frac{f(xh)-f(x)}{h},$ enter the expression needed to find the derivative function.

$f^{\text{'}}(x)=\underset{h0}{lim}$

$$

After evaluating this limit$,$ we see that $f^{\text{'}}(x)=\frac{df}{dx}=$

Finally, the equation of the tangent line to $f(x)$ where $x=2$ is $$
