The Slope of a Curve at a Point. Using the definition of derivative of a function at a point, $f'(a) = \lim_{h\to 0} \frac{f(a+h) - f(a)}{h}$, find the slope of the curve at the given points or state that the slope is undefined. $f(x) = \frac{14}{x+3}$ At $a = 0$, the slope is At $a = -3$, the slope is undefined Note: type 'undefined' if you think the slope of the curve is undefined at the given points.
