[tex]\frac{4-x}{20}[/tex]Ответ:
y кас.= F(a)+F'(a)(x-a)
F(a)=[tex]\frac{1}{5a}[/tex]
F'(a)= [tex]-\frac{1}{5a^{2} }[/tex]
y кас.=[tex]\frac{1}{5a}[/tex]+[tex]-\frac{1}{5a^{2} }[/tex](x-2)=[tex]\frac{1}{5a} }-\frac{x}{5a^{2} }+\frac{2}{5a^{2} }=\frac{a}{5a^{2} } }-\frac{x}{5a^{2} }+\frac{2}{5a^{2} }=\frac{a-x+2}{5a^{2} }[/tex]=[tex]\frac{4-x}{20}[/tex]
Ответ: у кас. =[tex]\frac{4-x}{20}[/tex]
