a$)$ Graph the function $f(x)=\frac{8}{x}.$

b$)$ Draw tangent lines to the graph at the points whose $x-$coordinates are $0$ and $1.$

c$)$ Find $f^{\text{'}}(x)$ by determining $\underset{h0}{lim}\frac{f(x+h)-f(x)}{h}.$

d$)$ Find $f^{\text{'}}(0)$ and $f^{\text{'}}(1).$ These slopes should match those of the lines from part $($b$).$
