Find \(\ds \lim_{h\to 0}\frac{f(1+h)-f(1)}{h}\) where \(\ds f(x)=\frac{3x+1}{x-2}\text{.}\) What does the result in (a) tell you about the tangent line to the graph ...

A spinoff for Michelle Yeoh’s character from the “Discovery” series, whose frequent director Olatunde Osunsanmi again takes the reins here, this superficially diverting tangent is too ...
