Use limits to find $\frac{dy}{dx}$ if $y=8x^2.$ Then evaluate $\frac{dy}{dx}{|}_x|=7$ and $\frac{dy}{dx}{|}_x|=-4.$

Identify the limit that should be evaluated in order to find $\frac{dy}{dx},$ using h and not using fin your answer."

$\frac{dy}{dx}=\underset{h0}{lim}\frac{8(xh{)}^2-8x^2}{h}$

Find the function for $\frac{dy}{dx}.$

$\frac{dy}{dx}=$
